This is my second lecture on 2D graphics, it covers Drivers, Modes, and APIs.

contourlet 小波，直方图的三种图像增强程序(failed to translate)

说明：  一种二值水印嵌入的方法，个人编写的，里面还有ppt，及Arnold置乱算法(a watermark embedded value method, personal preparation, there is also ppt, and Arnold Scrambling Algorithm)

根据降雨数据和流量数据，可在同一张图上绘制倒立的降雨柱状图和对应的流量过程线(According to rainfall data and flow data, inverted rainfall column charts and corresponding flow process lines can be drawn on the same chart.)

说明：  snakes算法简单程序（可运行），对初步学习snakes算法有帮助(snakes simple algorithm (runs), the preliminary study snakes help Algorithm)

字符权的匹配的算法 The algorithm for matching character rights(Right of character matching algorithm, The algorithm for matching character does)

vb 饼状图和柱状图，这里是一个demo，并含有注释，方便新手学习(vb,circle chart and point chart)

说明：  在图像上画一条线，提取所在位置的像素。主要是用来观察横向异质性变化的。(Draw a line on the image and extract the pixels at the location. Mainly used to observe changes in lateral heterogeneity.)

数字图像非局部均值算法，很好的哦。我自己试过了

说明：  顶帽变换的程序，能够实现平滑图像的效果。(Cap transformation process, to achieve the effect of smoothing the image.)
