An Image Compression-Encryption Algorithm Based on Compressed Sensing and Chaotic Oscillator,scillator are applied in a compression-encryption algorithm. Here, we propose an image compression-encryption method using compressed sensing and a chaotic oscillator. At first, the original image is represented in the wavelet domain to obtain sparse coefficients. The sparse representation is scramb
