convex

说明：  用2种方法，对text.png图像中的字母‘a’进行定位，给出定位结果以及位置坐标。(Two methods were used to locate the letter 'a' in the image of text. PNG, and the location result and position coordinates were given.)

在图像边缘点上计算边缘法向量, Compute the norm vector at the boundary(compute the norm vector at the boundary)

说明：  实现洛伦兹系统分岔图的三种方法，最大值法，庞加莱截面法，getmax法(Three Methods to Realize Lorentz System Bifurcation Diagram)

利用matlab的DCT2函数，对图像做变换并压缩。并用8*8对图像分块，对每一块计算均方值作为阈值。(DCT2 use the matlab function, and transform the image so compressed. And 8* 8 image block, a calculation of each mean square value as a threshold.)

说明：  matlab实现均值滤波，中值滤波，同时操作(Matlab to achieve mean filtering, median filtering)

说明：  本代码实现了K均值聚类，代码简单易懂，容易初学者学习(This code realizes K-means clustering, the code is easy to understand, easy for beginners to learn)

dish tracking techniques

实现中值滤波的源程序 参数Hori是一个布尔变量，若为真，做水平中值滤波，否则，做竖直中值滤波。(achieve Median filtering of the source parameters Hori is a Boolean variable, if true, so the level of median filtering, otherwise, do vertical median filtering.)
