DBSCAN是一个基于密度的聚类算法。改算法将具有足够高度的区域划分为簇，并可以在带有“噪声”的空间数据库中发现任意形状的聚类。-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

The indexing of an image database is often referred as feature extraction. Mathematically, a feature is an n-dimensional vector, with its components computed by some image analysis. The most commonly used visual cues are color, texture, shape, sp
