fft
- 利用傅里叶变换对图像进行降低噪声处理，而且内附有高通和低通滤波功能-Fourier transform
testfft
- opencv实现对图像fft变换和逆变换，画出傅里叶变换谱-opencv realized the image fft transform and inverse transform, Fourier transform spectrum plot
watermarkfft
- 基于fft的数字水印，分别对RBG三个通道重复嵌水印，每个通道分别对fft变换域中幅度谱以圆方式，每个圆上对称的四个点重复嵌1bit水印，然后以r为步进，选更大的圆嵌入接下去的水印信息，该方法有比较好的鲁棒性-Fft-based digital watermarking were embedded watermark repeated RBG three channels, each channel separately the fft transform domain amplitude sp
opencvfft
- 采用OPENCV库来对图片进行按列依次进行FFT变换，并将结果保存。-The OPENCV library to FFT transform, according to orderly images and save the results.
