eBook Download

BOOK EXCERPT:

The first project, leveraging libraries like OpenCV, Pillow, imageio, and Matplotlib, offers a streamlined interface for analyzing RGB histograms from video files. The main window is initialized using the AnalyzeHistogramFrame class, where users interact with buttons, labels, and canvases. Upon loading a video file via the "Open Video" button, the open_video() method utilizes imageio to display the first frame in the GUI canvas. Playback controls such as "Play/Pause" and "Stop" manage the video's playback state, with the show_frame() method continuously updating the displayed frame. Users can engage with the frame by zooming with the mouse wheel or defining a region of interest (ROI) through click-and-drag actions. Upon releasing the mouse button, the analyze_histogram method extracts the ROI, displaying it alongside its RGB histogram in a separate window, courtesy of Matplotlib. The histogram analysis process involves plotting individual RGB channel histograms, combined into a unified histogram. These plots are converted into Tkinter-compatible images for seamless integration into the GUI, empowering users with a comprehensive tool for visualizing and exploring video frame data. The second project is a Python application built with Tkinter, a GUI library, to enable users to analyze RGB histograms of the filtered of cropped image of a certain frame. It combines several libraries like PIL, imageio, OpenCV, NumPy, and Matplotlib to provide a comprehensive interface and analytical capabilities. The application's structure revolves around a class named Filter_CroppedFrame, responsible for managing the GUI and functionalities. Initially, the script imports necessary libraries and defines the Filter_CroppedFrame class. This class initializes the main window, sets up attributes, and creates GUI elements such as buttons, comboboxes, and canvas for video display. Users can load video files using a file dialog, which triggers the open_video() method to load the video via imageio. Playback controls for play, pause, and stop are provided, managed by methods like play_video(), toggle_play_pause(), and stop_video(). The show_frame() method updates the displayed frame based on the playback state and zoom level. Interactive analysis is facilitated through user interactions like zooming and drawing bounding boxes, handled by methods such as on_mousewheel(), on_press(), on_drag(), and on_release(). After drawing a bounding box and releasing the mouse button, the analyze_histogram method is called to extract the cropped region, apply selected filters, and display the cropped image with its RGB histogram in a popup window. The application supports various filters like Gaussian, mean, median, bilateral, and wavelet transforms, applied via the apply_filter() method, with filter selection facilitated by GUI elements like comboboxes. The script concludes with a main function initializing the application by creating an instance of the Filter_CroppedFrame class and starting the main event loop, enabling seamless GUI responsiveness and analysis tasks execution. The third project centers around a GUI application designed to facilitate edge detection within cropped images sourced from video files. Developed using Tkinter, the application boasts an array of interactive elements such as buttons, labels, and comboboxes to enhance user experience and functionality. At its core, the Edges_CroppedFrame class governs the application's operations, initializing critical attributes and orchestrating the creation of graphical components. A key feature of the application lies in its robust handling of video files. Users can effortlessly load video files via a file dialog interface, leveraging the imageio library for efficient frame extraction. The seamless rendering of frames onto a Tkinter canvas forms the foundation of the GUI, allowing users to navigate frames, control video playback, and utilize zoom features through intuitive buttons and comboboxes. Central to the application's functionality is its capability for edge detection within defined regions of interest (ROIs) within frames. Leveraging the OpenCV library, the application seamlessly integrates various edge detection algorithms, including Canny, Sobel, Prewitt, Laplacian, Scharr, FreiChen, Roberts, Kirsch, and Robinson. Users can interactively select rectangular ROIs within frames using mouse-driven actions, with the application dynamically updating the displayed frame to showcase the selected ROI alongside its corresponding histogram. Furthermore, the application extends its utility by enabling concurrent processing of multiple videos. Users can spawn new instances of the application, facilitating comprehensive video analysis and edge detection tasks across different video files. This feature enhances versatility and scalability, catering to diverse user requirements and amplifying the application's utility for advanced video processing endeavors.

eBook Download

BOOK EXCERPT:

A DataFrame is a fundamental data structure in pandas, a powerful Python library for data manipulation and analysis, designed to handle two-dimensional, labeled data akin to a spreadsheet or SQL table. It simplifies working with tabular data by supporting various operations like filtering, sorting, grouping, and aggregating. DataFrames are easily created from lists, dictionaries, or NumPy arrays and offer flexible data handling, including managing missing values and performing input/output operations with different file formats. Key features include hierarchical indexing for multi-level grouping, time series functionality, and integration with libraries such as NumPy and Matplotlib. DataFrame manipulation encompasses filtering, sorting, merging, grouping, pivoting, and reshaping data, while also allowing custom functions, handling missing data, and managing data types. Mastering these techniques is crucial for efficient data analysis, ensuring clean, transformed data ready for deeper insights and decision-making. In chapter 2, in the first project, we filter a DataFrame named employee_data, which includes columns like 'Name', 'Department', 'Age', 'Salary', and 'Years_Worked', to find employees in the 'Engineering' department with a salary exceeding $70,000. We create the DataFrame using sample data and apply boolean indexing to achieve this. The boolean masks employee_data['Department'] == 'Engineering' and employee_data['Salary'] > 70000 identify rows meeting each condition. Combining these masks with the & operator filters the DataFrame to include only those rows where both conditions are met, resulting in a subset of employees who fit the criteria. The final output displays this filtered DataFrame. In second project, we filter a DataFrame named sales_data, which includes columns such as 'Product', 'Category', 'Quantity Sold', 'Unit Price', and 'Total Revenue', to find products in the 'Electronics' category with quantities sold exceeding 100. We use boolean indexing to achieve this: sales_data['Category'] == 'Electronics' creates a mask for rows in the 'Electronics' category, while sales_data['Quantity_Sold'] > 100 identifies rows where quantities sold are above 100. By combining these masks with the & operator, we filter the DataFrame to include only rows meeting both conditions. The final output displays this filtered subset of products. In third project, we filter a DataFrame named movie_data, which includes columns such as 'Title', 'Genre', 'Release Year', 'Rating', and 'Box Office Earnings', to find movies released after 2010 with a rating above 8. We use boolean indexing where movie_data['Release_Year'] > 2010 creates a mask for movies released after 2010, and movie_data['Rating'] > 8 identifies movies with ratings higher than 8. By combining these masks with the & operator, we filter the DataFrame to include only the rows meeting both conditions. The final output displays the subset of movies that fit these criteria. The fourth project demonstrates a Tkinter-based GUI application for filtering a sales dataset using Python libraries Tkinter, Pandas, and PandasTable. The application allows users to interact with a table displaying sales data, applying filters based on product category and quantity sold. The filter_data() function updates the table to show only items from the selected category with quantities exceeding the specified value, while the refresh_data() function resets the table to display the original dataset. The GUI includes input fields for category selection and quantity entry, along with buttons for filtering and refreshing. The sales data is initially presented in a PandasTable with a toolbar and status bar. Users interact with the interface, which updates and displays filtered data or the full dataset as needed. The fifth project features a Tkinter GUI application that lets users filter a movie dataset by minimum release year and rating using Python libraries Tkinter, Pandas, and PandasTable. The filter_data() function updates the displayed table based on user inputs, while the refresh_data() function resets it to show the original dataset. The GUI includes fields for entering minimum release year and rating, buttons for filtering and refreshing, and a PandasTable for displaying the data. The application allows for interactive data filtering and visualization, with the table initially populated with sample movie data. In the sixth project, a retail store manager uses a DataFrame containing sales data to identify products that are both popular and profitable. By applying logical operators to filter the DataFrame, the goal is to isolate products that have sold more than 100 units and generated revenue exceeding $5000. This filtering is achieved using the Pandas library in Python, where the & operator combines conditions to select the relevant rows. The resulting DataFrame, which includes only products meeting both criteria, provides insights for decision-making and analysis in retail management. The seventh project involves creating a Tkinter-based GUI application to manage and visualize sales data. The GUI displays data in a table and a bar graph, allowing users to filter products based on minimum quantity sold and total revenue. The application uses pandas for data manipulation, pandastable for table display, and matplotlib for the bar graph. The GUI consists of an input frame for user filters and a display frame for showing the table and graph side by side. Users can update the table and graph by clicking "Filter Data" or reset them to the original data with the "Refresh" button, providing an interactive way to analyze sales performance. In chapter three, the first project demonstrates how to sort synthetic financial data for analysis. The code imports libraries, sets random seeds for reproducibility, and generates data for businesses including revenue and expenses. It then creates a DataFrame with this data, sorts it by monthly revenue in descending order, and saves the sorted DataFrame to an Excel file. This process aids in organizing and analyzing financial data, making it easier to identify top-performing businesses. The second project creates a Tkinter GUI to view and interact with synthetic financial data, displaying monthly revenue and expenses for various businesses. It generates random data, stores it in a DataFrame, and sets up a GUI with two tabs: one for sorting by revenue and another for expenses. Each tab features a table to display the data and a matplotlib plot for visual representation. The GUI allows users to sort and view data dynamically, with alternating row colors for readability and embedded plots for better analysis. The third project generates synthetic unemployment data for 10 regions over 5 years, sets random seeds for reproducibility, and creates a DataFrame with the data. It then sorts the DataFrame alphabetically by region and saves it to an Excel file named "synthetic_unemployment_data.xlsx". Finally, the script prints a confirmation message indicating that the data has been successfully saved. The fourth project generates synthetic unemployment data for 25 regions over a 5-year period and creates a Tkinter GUI for interactive data exploration. The data, organized into a DataFrame and saved to an Excel file, is displayed in a tabbed interface with two views: one sorted by unemployment rate and another by year. Each tab features scrollable tables and corresponding bar charts for visual analysis. The UnemploymentDataGUI class manages the interface, updating tables and graphs dynamically to allow users to explore regional and yearly unemployment variations effectively. The fifth project demonstrates how to concatenate dataframes with synthetic temperature data for various countries. Initially, we generate temperature data for countries like the USA and Canada for each month. Next, we create an additional dataframe with temperature data for other countries such as the UK and Germany. We then concatenate the original and additional dataframes into a single dataframe and save the combined data to an Excel file named combined_temperatures.xlsx. The steps involve generating synthetic data, creating additional dataframes, concatenating them, and exporting the result to Excel. The sixth project demonstrates how to build a Tkinter application to visualize synthetic temperature data. The app features a tabbed interface with tabs for displaying raw data, temperature graphs, and filters. It uses alternating row colors for better readability and includes functionality for filtering data by country and month.

The seventh project demonstrates how to perform an inner join on two synthetic dataframes: one containing housing details and the other containing owner information. First, synthetic data is generated for houses and their owners. The dataframes are then merged on the common key, HouseID, using an inner join to include only rows with matching keys. Finally, the combined data is saved to an Excel file named combined_housing_data.xlsx. The result is an Excel file that contains details about houses along with their respective owners. The eight project provides an interactive platform for managing and visualizing synthetic housing data. Users can view comprehensive tables, apply filters for location and house type, and analyze house price distributions with Matplotlib plots. The application includes tabs for displaying data, filtering results, and generating visualizations, with functionalities to reset filters, save filtered data to Excel, and ensure a user-friendly experience with alternating row colors in tables and dynamic updates. To demonstrate an outer join on DataFrames with synthetic medical data, in ninth project, we create two DataFrames: one for patient information and another for medical records. We then perform an outer join to ensure all patients and records are included, even if some records don't have corresponding patient data. The code generates synthetic data, performs the outer join using pd.merge() on the PatientID column, and saves the result to an Excel file named outer_join_medical_data.xlsx. This approach provides a comprehensive dataset with complete patient and medical record information. The tenth project involves creating a Tkinter-based desktop application to visualize and interact with synthetic medical data. The application uses an outer join to merge patient and medical record datasets, displaying the comprehensive result in a user-friendly table. Users can filter data by patient ID and condition, view distribution graphs of medical conditions, and save filtered results to an Excel file. The GUI, leveraging Tkinter and Matplotlib, includes tabs for data display, filtering, and graph visualization, providing a robust tool for exploring medical datasets. In chapther four, the first project demonstrates creating and manipulating a synthetic insurance dataset. Using numpy and pandas, the script generates random data including columns for Policyholder, Age, State, Coverage_Type, and Premium. It groups this data by State and Coverage_Type to show basic data segmentation, then saves the dataset to an Excel file for further analysis. The code provides a practical framework for simulating and analyzing insurance data by illustrating the process of data creation, grouping, and storage. The second project demonstrates a Tkinter GUI application designed for analyzing a synthetic insurance dataset. The GUI displays 1,000 records of policyholder data in a scrollable table using the Treeview widget, with options to filter by state and coverage type. Users can save filtered data to an Excel file and generate a bar plot of policy distribution by state, integrated into the Tkinter window using Matplotlib. This application provides interactive tools for data exploration, filtering, exporting, and visualization in a user-friendly interface. The third project focuses on creating, analyzing, and aggregating a large synthetic sales dataset with 10,000 records.

Wind Power Analysis And Forecasting Using Machine Learning With Python

eBook Download

BOOK EXCERPT:

In this project on wind power analysis and forecasting using machine learning with Python, we started by exploring the dataset. We examined the available features and the target variable, which is the active power generated by wind turbines. The dataset likely contained information about various meteorological parameters and the corresponding active power measurements. To begin our analysis, we focused on the regression task of predicting the active power using regression algorithms. We split the dataset into training and testing sets and preprocessed the data by handling missing values and performing feature scaling. The preprocessing step ensured that the data was suitable for training machine learning models. Next, we trained several regression models on the preprocessed data. We utilized algorithms such as Linear Regression, Decision Tree Regression, Random Forest Regression, and Gradient Boosting Regression. Each model was trained on the training set and evaluated on the testing set using performance metrics like mean squared error (MSE) and R-squared score. After obtaining regression models for active power prediction, we shifted our focus to predicting categorized active power using machine learning models. This involved converting the continuous active power values into discrete categories or classes. We defined categories based on certain thresholds or ranges of active power values. For the categorized active power prediction task, we employed classification algorithms. Similar to the regression task, we split the dataset, preprocessed the data, and trained various classification models. Common classification algorithms used were Logistic Regression, Support Vector Machines (SVM), K-Nearest Neighbors (KNN), Decision Trees, Random Forests, Gradient Boosting, Extreme Gradient Boosting, Multi-Layer Perceptron, and Light Gradient Boosting models. During the training and evaluation of classification models, we used performance metrics like accuracy, precision, recall, and F1-score to assess the models' predictive capabilities. Additionally, we analyzed the classification reports to gain insights into the models' performance for each category. Throughout the process, we paid attention to feature scaling techniques such as normalization and standardization. These techniques were applied to ensure that the features were on a similar scale and to prevent any bias or dominance of certain features during model training. The results of predicting categorized active power using machine learning models were highly encouraging. The models demonstrated exceptional accuracy and exhibited strong classification performance across all categories. The findings from this analysis have significant implications for wind power forecasting and monitoring systems, allowing for more effective categorization and management of wind power generation based on predicted active power levels. To summarize, the wind power analysis and forecasting session involved dataset exploration, active power regression using regression algorithms, and predicting categorized active power using various machine learning models. The regression task aimed to predict continuous active power values, while the classification task aimed to predict discrete categories of active power. Preprocessing, training, evaluation, and performance analysis were key steps throughout the session. The selected models, algorithms, and performance metrics varied depending on the specific task at hand. Overall, the project provided a comprehensive overview of applying machine learning techniques to analyze and forecast wind power generation.
