中心点漂移是一种非监督聚类算法（与k-means算法相似，但应用范围更广些),可用于图像分割，基于Matlab实现的源码。 MedoidShift is a unsupervised clustering algorithm(similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.(Center drift is a non-supervised clustering algorithm (k-means algorithm with the similar, but more a wider range of applications), can be used for image segmentation, based on the realization of the source Matlab. MedoidShift is a unsupervised clustering algorithm (similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.)

自己做的一个针对mdb中数据集构建拓扑，并进行拓扑验证的例子，之前找半天没有找到相关的，自己做的这个还是可以用的，希望能帮到有需要的人士(Examples of their own to do a build topology for mdb data sets and topology verification, before looking for a long time did not find the relevant own doing this can still be used, I hope to help those in need)

Students’ and Teachers’ Perceptions of Effective Foreign Language Teaching: A Comparison of Ideals ALAN V. BROWN

某石油公司计划建造一条由东向西的主输油管道。该管道要穿过一个有n 口油井的油田。从每口油井都要有一条输油管道沿最短路经(或南或北)与主管道相连。如果给定n 口油井的位置,即它们的x 坐标（东西向）和y 坐标（南北向）,应如何确定主管道的最优位置, 即使各油井到主管道之间的输油管道长度总和最小的位置?证明可在线性时间内确定主管道的最优位置。(An oil company plans to construct a east to west from the main pipeline. The pipeline to pass through an oil field n wells. Wells from each must have a pipeline along the shortest path (or South or North) connected with the competent Road. If given the location of oil wells in n, that is, their x coordinates (east-west) and y coordinates (north-south), should be how to determine the optimal position in charge of Road, even if the wells to the pipeline in charge of Road between the sum of the smallest length location? proved to be linear time to determine the optimal position in charge of Road.)

说明：  图像的几种锐化处理，包括sobel算子，roberts梯度法和laplace算子锐化。并且将四种图像放在一起形成对比。(Several image sharpening, including sobel operator, roberts gradient and laplace operator sharpening. And will contrast the four images together.)
