a Prototype and workflow of the reported optical encryption system. b Decryption comparison of conventional alternating projection (AP) algorithm, compressive sensing with total variation regularization (CS-TV) algorithm, deep learning (DL) algorithm, and the reported hybrid-driven algorithm (Ours). M and N represent the number of pixels in the length and width of the Rawdata images, respectively. P denotes the number of image frames acquired, and θ represents the compression ratios.
