Description: vb版本的fft变换，能够正反变换。正变换：
把时域信号转换成频域信号，反变换：能够把频域信号转换成时域信号。fft可广泛应用于工程领域，例如：信号的频域分析。震动，噪声的分析等等。-vb version of the fft transform, to transform pros. Transformation : put time domain signal into frequency domain signal, anti-transformation : can frequency-domain signal into time domain signal. Fft can be widely used in engineering fields, such as : the frequency-domain analysis. Vibration, noise analysis, and so on. Platform: |

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
-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 Platform: |
