[Delphi VCL] wavelet_JPEG2000 DL : 0: Delphi:基于小波的JPEG2000图像压缩技术实例，由Delphi源代码实现，内含了小波动态连接库（vc实现），Delphi可借用这个类库。　　首先必须注意的是，在小波变换的时候采用的是串行工作方式　　这样一来，对于高速缓存的利用是十分低效率的，却可以节省不少的空间。　　BIT.H BIT.C －是有关比特位操作的代码　　WAVELET.H WAVELET.C －是小波操作的代码　　　　函数输出：函数返回转换象素的数目　　1) Num：需要转换的连续象素的署名女　　3)Y, Cb, Cr：同样是指针，分别指向三个结果的存放空间 -Delphi: JPEG2000 wavelet-based image compression techniques instance, achieved by the Delphi source code that contains the wavelet dynamic link library (vc achieve), Delphi can borrow this library. First, it must be noted that, when the wavelet transform is used in a serial mode of operation Thus, the use of cache efficiency is very low, it can save a lot of space. BIT.H BIT.C- is a bit of code related operations WAVELET.H WAVELET.C- is the code of wavelet operations Output function: The function returns the number of pixels to convert 1) Num: women need to convert signature consecutive pixels 3) Y, Cb, Cr: same pointer, pointing to three storage space results
