  • 相位迭代加密
    利用分数阶傅里叶变换的方法,通过迭代相位将加密图像替换为所需要的相位达到加密效果,上传压缩包包括代码和图片,不需要任何修改即可运行。(Using a fractional Fourier transform, the iterative phase replaces the encrypted image with the required phase to achieve the encryption effect. Uploading the compressed package includes the code and picture, and it can be operated without any modification.)
