A general technique for the recovery of signi cant image features is presented. The technique is based on the mean shift algorithm, a simple nonparametric pro- cedure for estimating density gradients. Drawbacks of the current methods (including robust clustering) are avoided. Feature space of any nature can be processed, and as an example, color image segmentation is dis- cussed. The segmentation is completely autonomous, only its class is chosen by the user. Thus, the same program can produce a high quality edge image, or pro- vide, by extracting all the signi cant colors, a prepro- cessor for content-based query systems. A 512 512 color image is analyzed in less than 10 seconds on a standard workstation. Gray level images are handled as color images having only the lightness coordinate

「新聞群聚」就是一項(xiàng)需要人力介入的新聞服務(wù)，而為了使其更為自動(dòng)化，我們將文件分群（document clustering）的技術(shù)應(yīng)用在新聞文件上，達(dá)到新聞分群（news clustering）的目的。

DBSCAN是一個(gè)基于密度的聚類算法。改算法將具有足夠高度的區(qū)域劃分為簇，并可以在帶有“噪聲”的空間數(shù)據(jù)庫(kù)中發(fā)現(xiàn)任意形狀的聚類。-DBSCAN is a density-based clustering algorithm. Algorithm change will have enough height to the regional cluster. and to be with the "noise" of the spatial database found clusters of arbitrary shape.

中心點(diǎn)漂移是一種非監(jiān)督聚類算法（與k-means算法相似，但應(yīng)用范圍更廣些),可用于圖像分割，基于Matlab實(shí)現(xiàn)的源碼。 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.
