主程序main.m:以8比特的格式读入一幅BMP格式的图片,创建一个main的JPEG格式文件,然后写入JPEG的标记码(Tag),写入后,调用压缩函数compression。得到压缩数据的二进制码流,将得到的码流写入文件,再将标记码的EOI标志写入文件。最后将JPEG图象显示在界面上。整个程序结束。 compresion.m压缩函数: 输入:BMP图象数据。 输...
It shows what a jpeg compression is all about. The function implements the DCT transform, using a matrix operator. Note that MATLAB has a function for the DCT and iDCT transforms that might be more efficient. read the ReadMe.txt for some details about the algorithm. If you like this ...
