Compression and decompression using huffman code

该文档详细描述了JPEG编码过程，涉及色系变换、DCT变换、量化、Huffman编码等关键步骤，适合JPEG编码入门学习。-The document is a detailed descr iption of the JPEG encoding process involves color transform, DCT transform, quantization and Huffman coding key steps, learning portal for JPEG encoding.

根据BMP图像的特点提出了基于Huffman编码的压缩方法分别采用RGB统一编码和RGB分别编码两种方式对图像进 行压缩和解压程序设计然后对多幅图像进行了压缩和解压实验最后对实验结果进行了相关的分析-Joint Optimization of Run-Length Coding, Huffman Coding, and Quantization Table With Complete Baseline JPEG Decoder Compatibility
