WebFeb 27, 2024 · Recently, compressive sensing (CS) schemes have been studied as a new compression modality that exploits the sensing matrix in the measurement scheme and …
WebAt present, most image encryption algorithms protect the security of the plain images by encrypting them into visually meaningless cipher images similar to noises. However, noise-like images can easily attract the attention of an attacker, thus increasing the risk of being broken. Based on this, a visually meaningful image encryption algorithm based on … WebCompressed Sensing (CS) is a mathematical framework to reconstruct MR images from sparse data to minimize the data acquisition time. Image sparsity is the key in CS to …
