说明：  此程序给出由三个不同频率的正弦所组成信号的联合时－频分布。该图是三维图形的二维投影，在该图中，一个轴是时间，一个轴是频率。由该图可清楚地看出信号的时间－频率关系。(This program shows three different frequency sinusoidal signal composed of joint time- frequency distribution. The plan is two-dimensional projection three-dimensional graphics in the figure, one axis is time, an axis is frequency. By the diagram is clear that the signal of the time- frequency relation.)

MATLAB图像增强程序举例,灰度变换增强程序,直方图灰度变换,直方图均衡化程序举例d等(MATLAB image enhancement program for example, enhanced gray-scale transformation program, histogram gray level transformation, histogram equalization and other programs for example d)

数字水印中，对于水印的置乱方法：Arnold置乱，通过改变像素点的位置增强水印的鲁棒性(Digital watermark, the watermark scrambling for ways: Arnold scrambling, by changing the position of pixels increase the robustness of the watermark)

DIFFERENT METHODS FOR DETECTING OUTLIERS

Gold 序列产生程序，产生序列的长度n，主要用于扩频代码中(gold sequence)
