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

可以完成灰度图像的算术编码和解码,来完成二维图像在matlab中的压缩处理-You can complete the grayscale image arithmetic encoding and decoding, to complete the two-dimensional image compression processing in matlab

用matlab实现MPEG压缩编码，对图像编码率失真性能进行分析，比较不同类型静态图像编码效率。 -Using Matlab to achieve MPEG compression coding, image coding rate distortion performance analysis, compare the different types of static image coding efficiency.

matlab读取grib文件安装包必备，grib文件是与计算机无关的压缩的二进制编码,主要用来表示数值天气预报的产品资料(Matlab reads grib file installation package)
