Image Processing Techniques: Binarization, Canny Edge Detection, ROI Extraction, and Automatic Multi-Threshold Segmentation

This documentation presents a collection of image processing programs covering essential techniques such as binarization using global/local thresholding methods, Canny operator edge detection with gradient calculation and non-maximum suppression, region of interest (ROI) extraction through mask operations, and automatic multi-threshold segmentation employing histogram analysis algorithms. Additionally, we include two technical articles discussing watershed segmentation implementation with marker-controlled approaches and connected component analysis for character recognition using region labeling and feature extraction. These programs and articles provide comprehensive tools and methodologies for advanced image analysis and character recognition tasks. Through these techniques, we can effectively detect image edges, isolate specific regions, and extract character features using morphological operations and pattern recognition algorithms. This comprehensive approach enables improved results in digital image processing and optical character recognition applications.
