A joint image encryption and watermarking algorithm based on compressive sensing and chaotic map |
Decrypted images and the extracted watermarks when the ciphered image is affected by noise: (a) 1% Gauss noise; (b) 1% salt and pepper noise; (c) 2% Gauss noise; (d) 2% salt and pepper noise; (e) 1% Gauss noise; (f) 1% salt and pepper noise; (g) 2% salt and pepper noise; (h) 2% salt and pepper noise. |
