利用傅里叶变换实现两幅大小相同的RGB图像的水印嵌入。包含水印的大小处理，水印嵌入和提取，以及对PNSR的计算。-Fourier transform two of the same size of the RGB image watermark embedding. Contains the size of the watermark processing, the watermark embedding and extraction, as well as on the PNSR the ca

The Fast Fourier Transform (FFT) is one of the rudimentary operations in field of digital signal and image processing. Some of the very vital applications of the fast fourier transform include Signal analysis, Sound filtering, Data compressio
