摘　　要：提出一种新的方法-基于法向量差值的区域生长,还提出了在候选种子中选择种子的方法,根据一种新的二面角的公式即法向量面积加权的差值进行区域生长,分割后对面积过小的面片区域进行优化处理。实验表明该方法快速有效。A new region growth based on segmentation algorithm is proposed.The method is on the basis of the difference of normal and choosing the seeds from the candidates.A new formula,the difference of normal with the area,is taken as the criterion of region growth.Small patch is optimized after segmentation.Experiments illustrate that this algorithm is fast and effective.
