Image Segmentation with JSEG Algorithm and Region Growing Methods

This code implements Digital Image Processing (DIP) image segmentation using the JSEG algorithm approach. The segmentation and color quantization process employs JSEG methodology combined with region growing techniques for image partitioning. The JSEG algorithm analyzes color and texture characteristics to divide images into distinct homogeneous regions through a two-stage process: first performing color quantization to reduce the color space, then applying spatial segmentation using J-segment validity measures. Region growing methods operate by comparing pixel similarity metrics, typically starting from seed points and iteratively merging adjacent pixels based on color and texture similarity thresholds. These techniques enable effective object extraction from background elements and facilitate meaningful image analysis. The implementation typically involves key functions for color space conversion, quantization table generation, and region merging criteria evaluation, providing robust tools for computer vision applications and image understanding.
