于傅里叶变换的图像加密技术研究
具体是将一幅图像用 fft 变换到频域
在频域中进行加密 我考虑的是通过随机相位来加密的方法,请问用matlab怎样实现
加密后在通过 ifft 得到加密后的图象
-Fourier transform in the image encryption technology to study the details of an image is to use fft transformed to the frequency domain in the frequency domain I consider encryption is through random-phase approach to encryption, Will the use of Matlab how to achieve the adoption of encryption ifft be encrypted images

比较五种窗函数特性matlab程序:得到矩形窗、海明窗、三角窗、汉宁窗和布莱克曼窗图形。从仿真结果可知:矩形窗设计的过渡带最窄,但阻带最小衰减也最差。布莱克曼窗设计的阻带最小衰减最好,但过渡带最宽。-Comparison of characteristics of five kinds of window function matlab program: to be a rectangular window, Hamming window, triangular window, Hanning window and Blackman window graphics. From the simulation results we can see: the rectangular window designed for narrow transition zone, but the minimum stop-band attenuation is also the worst. Blackman window design of the stop-band minimum attenuation is best, but the transitional zone widest.
