常用的小波变换、傅立叶变换、离散余弦变换、图像旋转、平移、缩放类模块，用户只需运行时只需调用相应的模块，这是我从我们开发的系统中剥离出来的类模块，供大家使用，希望大家能喜欢！-commonly used wavelet transform, Fourier transform, discrete cosine transform, image rotation, translation, scaling type module, users can run only when the corre

图像的DCT（离散余旋）和FFT（傅立叶）变换。-The image DCT (Discrete I spin) and FFT (Fourier) transformation.

5*5的中值旋滤波，以前在这下的旋滤波发现有点问题，改了一下-5* 5 median spin filtering, spin under the previous filter in this issue found that a little bit, changed a bit
