In order to detect the boundary points of clusters, this paper proposes the concept of grid's gradient and boundary grid, and a boundary points detecting algorithm called (Boundary Points detecting based Gradien of Grid,BPGG).BPGG detects boundary points of clusters according to grid's gradient.As shown by our experimental results,BPGG can be efficient and effective to detect boundary points and filter out noises in large datasets containing arbitary shaped clusters and noises.
