| 摘 要： | 根据混沌序列良好的随机性及灰度图像可分成若干位平面二值图的特点，提出了将混沌二值序列与位平面图像异或运算进行置乱，将置乱后的位平面图重新组合成灰度图，以此达到灰度图像置乱的效果。仿真结果表明，基于混沌与位平面的图像置乱方法可有效地使图像灰度值均匀化。

| Abstract: | According to the good randomness of the chaotic sequence and the characteristics of gray image which can be decomposed into several bit binary images, an ＂XOR＂ operation 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. |
