JPEG_compression_image.m
利用Matlab编程实现对lena.bmp灰度图象进行QF=50和QF=40的压缩和解压缩,比较二者的PSNR,并且利用霍夫曼编码模拟信道中传输图象。通过了Matlab2009A测试。(Using Matlab program to compress and decompress the gray image Lena.bmp at QF = 50 and QF = 40,as well as comparing the result of two situation.Then using Huffman coding analog channels transmitted images. Adopted Matlab2009A test.)

signalcompress
给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换,是FFT变换的近似,其正反变换相同,克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)
