将图象分块(8*8)，作DCT变换，并作IDCT：DCT是一种可分离图象变换，用来图象压缩编码，IDCT用来解压缩。(The image sub-block (8* 8) for the DCT transform, and to make IDCT: DCT is a separable image transformations, is used to image compression coding, IDCT is used to decompress.)

说明：  音频编解码，语音信号处理，乘法次数最少，可嵌入编码器(Audio codec, speech signal processing, the least number of multiplication can be embedded in the encoder)

好用的互信息程序，可以计算时序信号的互信息以及熵等。可以直接使用(it is used for multil-information,and it can be used directly.)
