我们研究了分数阶傅里叶变换特征值的多重性和复杂性,发现特征值的模糊性可能指示随机性。因此,我们提出了一种方法来随机化傅立叶变换。这种随机傅立叶变换可以应用于图像加密和解密领域。
We have investigated the multiplicity and complexity in eigenvalues of the fractional Fourier transform and found that the ambiguity of the eigenvalues may indicate randomness. We have therefore proposed a method to randomize the Fourier transform. Such a random Fourier transform can be applied in the field of image encryption and decryption.
