摘要
由于常规的高分辨率图像安全传输方法主要使用STDDS融合传输机制进行图像数据分块处理,易受量积矩阵相较多、张量积衰减的影响,导致图像信号存在约束等距问题,安全传输性能较差.因此,设计一种基于压缩感知的高分辨率图像安全传输方法.当传输图像的量积矩阵相对较多时,该方法进行张量积充足,构建高分辨率图像安全传输P张量积模型.假设离散传输信号中存在基矩阵,对其进行量化处理,生成原始信号压缩采样式;针对实际传输的图像信号存在一定的约束等距问题,利用CS算子进行重构求解,再利用压缩感知进行了图像安全传输补偿,从而实现了高分辨率图像安全传输.实验结果表明:设计的高分辨率图像安全传输方法的峰值信噪比、结构相似性指数均较高,未出现图像失真问题,因此可以得出,本文设计的高分辨率图像压缩感知安全传输方法的传输效果较好.
Abstract
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.
