个地进行量化和编码,达到压缩信息的作用. 离散余弦变换(DCT)在实数域中得到变换结果,并且有快速算法.-Using VC++ to achieve the digital image processing research in information processing and information transmission, in order to improve the efficiency of processing and transmission of information loss and reduce the need for large amounts of information coding. Digital Image Processing in the compressed transform domain coding techniques is image signal to image data block as a unit for two-dimensional transform, and then one by one of the transform coefficients to be quantified and coded, to reduce the role of information. discrete cosine transform (DCT) domain in the real results have been changing, and fast algorithm.
