基于非标准傅里叶变换光学编码技术的研究

The research of image encoding based on abnormal Fourier transform

侧重研究了非标准傅里叶变换编码技术在光学图像信息编码中的应用,结合Javidi提出的双随机相位编码原理,将这种加密变换应用到图像编码中,并提出了相应可行的光学实现装置.

Asymmetric abnormal Fourier transform, and emphasis its applications to image encoding. The proposed method is based on that it can append the distance between the lens as additional keys combined with Javidi proposed double random phase encoding principle, for the purpose of improving the system security to some extent and we expect its momentous practical application.
