This project processes 2D geometric shapes from CSV files, visualizing them as PNG and SVG files. It uses Python libraries like OpenCV and Matplotlib to detect and classify shapes such as triangles, rectangles, and circles, drawing contours and boundaries for clear identification and visualization.

2D Shape Processing and Visualization Project Overview This project is designed to process 2D geometric shapes extracted from CSV files, visualize them as PNG images, convert them into SVG files, and detect and classify shapes using OpenCV. The project utilizes Python libraries such as OpenCV, Matplotlib, NumPy, and svgwrite.

Features CSV Parsing: Reads and organizes 2D path coordinates from CSV files. PNG Visualization: Plots the extracted paths and saves them as PNG images. SVG Conversion: Converts the 2D paths into SVG format for scalable vector graphics. Shape Detection: Detects and classifies shapes (e.g., triangles, squares, circles) within the PNG images using OpenCV. Boundary Marking: Draws contours and bounding boxes around detected shapes for clear visualization. Dependencies Python 3.x OpenCV (cv2) NumPy Matplotlib svgwrite Install the required packages using pip:

bash Copy code pip install opencv-python numpy matplotlib svgwrite Usage Prepare the CSV File:

Ensure your CSV file contains 2D coordinates in the expected format. Run the Script:

Update the csv_path, png_path, and svg_path variables with your file paths. Execute the script to process and visualize the shapes. python Copy code

Example usage:

csv_path = 'path/to/your.csv' png_path = 'output_image.png' svg_path = 'output_image.svg'

Read CSV, plot, and save as PNG

paths_XYs = read_csv(csv_path) plot_and_save(paths_XYs, png_path)

Convert to SVG (optional)

polylines2svg(paths_XYs, svg_path)

Detect shapes and display

detect_shapes(png_path) Shape Detection and Visualization: The detected shapes are displayed with contours and annotated labels indicating the shape type. Functions read_csv(csv_path): Reads and organizes 2D coordinates from a CSV file. plot_and_save(paths_XYs, png_path): Plots paths and saves them as a PNG image. polylines2svg(paths_XYs, svg_path): Converts paths into an SVG file. detect_shapes(png_path): Detects shapes within the PNG image using OpenCV.
