A secure transmission method for high-resolution images based on compressed sensing
Because the conventional high resolution image security transmission method mainly uses STDDS fusion transmis-sion mechanism for image data block processing,it is susceptible to the influence of quantity product matrix and tensor product at-tenuation,resulting in the constraint problem of image signal,and the security transmission performance is poor.Therefore,a high-resolution image secure transmission method based on compressed sensing is designed.When there are relatively many quantita-tive product matrix of transmitted images,this method performs sufficient tensor product to construct a secure transmission P tensor product model of high-resolution images.Assuming the base matrix in the discrete transmission signal,to generate the original sig-nal compression pattern,use CS operator to reconstruct and solve the compressed sensing to realize the high resolution image trans-mission.The experimental results show that the peak signal to noise ratio and structural similarity index of the designed high-resolu-tion image secure transmission method are high,without the image distortion problem,so the designed high-resolution image com-pression sensing secure transmission method is good.
