db4小波变换，以及，db4小波逆变换！ 时间复杂度：O（n * log n）！！！ 推荐！-wavelet transform----db4

可伸缩视频中的5_3小波变换。运动补偿时间滤波是一种有效的可伸缩视频编码方案,采用5 /3提升小波实现能进一步提高其编码性能-Scalable video in the wavelet transform 5_3. Time motion compensation filter is an effective scalable video coding schemes, using 5/3 lifting wavelet to achieve further improve its coding

包括了小波变换、canny算子、robot算子、LOG算子、等等一系列边缘检测算子、可以应用这些对图像进行对比试验。有很强的应用性能。很不错的东西-Including wavelet transform, canny operator, robot operator, LOG operator, so a series of edge detection operators can apply these image comparison test. Strong application per

很好用的Log-Gabor变换源代码，可以用于图像的特征提取-Good use of Log-Gabor transform source code, can be used for image feature extraction
