Detailed Documentation
This program provides a robust implementation of JPEG image encoding and decoding, enabling seamless conversion of images to and from the JPEG format. The system employs carefully optimized algorithms including discrete cosine transform (DCT) for frequency domain conversion, quantization matrix processing for compression optimization, and Huffman coding for efficient entropy encoding. Through mathematical transformations and color space conversion (RGB to YCbCr), the implementation maintains high image quality while achieving significant file size reduction. The decoder component precisely reverses these operations using inverse DCT and dequantization processes to reconstruct images with minimal quality loss. This well-structured MATLAB code offers efficient image processing capabilities suitable for both personal use and commercial applications, providing reliable performance for various image manipulation requirements.
