数字图像 压缩算法-A LZW Compress algorithm used in digital image Process.

2D-DCT 压缩图像后，通过QPSK,AWGN信道编码传输后，IDCT解压缩回原始图像，适用于任何图像-Using DCT to compress the orginal image, I use zigzag program, quantization, dct compression, then change the vector to bineary bit to pass through the QPSK channel. And from the binary array, I us

在visual studio2005开发环境下，对图像进行霍夫曼编码、香农—费诺编码、算术编码和位平面编码。-In visual studio2005 development environment, compress images by Huffman coding, Shannon- Fenno coding, arithmetic coding and bit-plane coding.
