The key to the discussion is placedon the growth districts of thick-grain-size diamond and their thermodynamic conditions.

Study of improved region-growing algorithm used in ultrasound medical image segmentation

Method:Pretreating the images acquired from MR apparatus using threshold method,segmenting the images using region-growing arithmetic,and then reconstructing the model by using 3-dimension interpolations.

Focusing on detail preserving in triangle mesh model simplification,matching of the local average size of meshes surrounding a vertex or a triangle is taken as the criterion of region growth,and the matching threshold is lowering down in proportion to the increment of mesh density in a region.

An image segmentation method based on silhouettes of interested region is proposed in this paper because the segmentation problem of wasting time and illegibility of region′s boundary,which method is combined with edge detection and region growth.

The global motion estimation,extraction of object background,three-frame-difference technology and region growth method are used to extract moving object from video.
