Description: 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

Description: 实验目的:
1) 图像水平集合
2) 图像加密算法
3) 边缘提取
4) 噪音图像的产生
(2)显示图像,理解图像的模型
(3)使用图像的不同格式,理解图像压缩的意义
(4)对图像做简单的操作
本次实验需要熟练使用以下几个MATLAB命令:
imread, imwrite, imshow,figure
-Experimental purposes: 1) the level of collection of image 2) image encryption algorithm 3) Edge 4) noise generated images (2) display images, understanding image model (3) the use of images in different formats, understanding the significance of image compression (4) image to do a simple experiment needs to operate the skilled use of the following MATLAB command: imread, imwrite, imshow, figure Platform: |
