Description: 实现聚类K均值算法： K均值算法：给定类的个数K，将n个对象分到K个类中去，使得类内对象之间的相似性最大，而类之间的相似性最小。 缺点：产生类的大小相差不会很大，对于脏数据很敏感。 改进的算法：k—medoids 方法。这儿选取一个对象叫做mediod来代替上面的中心 的作用，这样的一个medoid就标识了这个类。步骤： 1，任意选取K个对象作为medoids（O1,O2,…Oi…Ok）。 以下是循环的： 2，将余下的对象分到各个类中去（根据与medoid最相近的原则）； 3，对于每个类（Oi）中，顺序选取一个Or，计算用Or代替Oi后的消耗—E（Or）。选择E最小的那个Or来代替Oi。这样K个medoids就改变了，下面就再转到2。 4，这样循环直到K个medoids固定下来。 这种算法对于脏数据和异常数据不敏感，但计算量显然要比K均值要大，一般只适合小数据量。-achieving K-mean clustering algorithms : K-means algorithm : given the number of Class K, n will be assigned to target K to 000 category, making target category of the similarity between the largest category of the similarity between the smallest.

本補丁提取自MOTO Q8！
感謝研究者提供！
經親測後
o2 stealth測試可用!!!!!
但好像大多數HTC機不能用!!大家試試！！
使用介紹!!!!!!
<<把CAB直接安裝,,,之後開WMP就可以播放了!!!>>
一般640*480，300左右KBS RM/RMVB順暢播放
較高畫質以及AAC音頻有時會比較卡
-[Reprint] RM/RMVB decoder for wm5/6 windows media player!!! This patch extracted from the MOTO Q8! Thank the researchers! Measured by the pro-test can be used after the o2 stealth !!!!! but like most of HTC machines can not be used!! Try U.S.! ! Introduction to use !!!!!! < < to install the CAB directly, and then open WMP can play a general 640* 480,300 !!!> > about KBS RM/RMVB playback smoother high-definition, as well as AAC audio has When more cards

Description: 了一种基于融合和广义高斯模型的遥感影像变化检测算法。该算法融合差值影像和比值影像的结
果构造差异影像，然后运用灰度形态学对差异影像进行顾及空间邻域关系的处理，再对处理后的结果运用广义高
斯分布模型估计变化与非变化像元的概率密度参数，最后采用改进的O2 算法计算最佳分割阈值，提取变化区域。
实验结果表明，所提出的变化检测算法稳健、高效，具有较大的实用价值。-0LDI TCTUG TGUIUNVI C MLCNEU WUVUMVD5N CTTG5CML 5X GUB5VU IUNIDNE DBCEUI YCIUW 5N XFID5N CNW
