According to the good randomness of the chaotic sequence and the characteristics of gray image which can be decomposed into several bit binary images,anXORoperation between binary chaotic sequence and bit image is proposed to be scrambling.The bit images after scrambling are recombined to be gray image,so that the effect of the gray image scrambling is realized.The simulation results show that the image scrambling algorithm based on chaos and bit image can homogenize the image gray effectively.
