Image compression-encryption method based on two-dimensional sparse recovery and chaotic system
Abstract In this paper, we propose an image compression-encryption method based on two-dimensional (2D) sparse representation and chaotic system. In the first step of this method, the input image is extended in a transform domain to obtain a sparse representation. To achieve better performance of im...
