混沌的一些具体行为，混沌的分岔等等理论，以及混沌的一些特征问题等等。(Some of the specific acts of Chaos, chaos theory of bifurcation, etc., as well as problems, and so some of the characteristics of chaos.)

说明：  (1) 打开一个bmp文件 (2) 将其局部区域的灰度值进行改变 (3) 另存为一个新的bmp文件 ((1) open a bmp file (2) the gray value of its local area to change (3) Save as a new bmp file)

说明：  对图像进行归一化处理！是图像预处理中不可缺少的重要部分(The image is normalized! Image preprocessing is an indispensable part in)
