摘要：matlab函数_连通区域1、 matlab函数bwareaopen──删除小面积对象格式：BW2 = bwareaopen(BW,P,conn)作用：删除二值图像BW中面积小于P的对象，默认情况下使用8邻域。算法：(1)Determine the connected components. L = bwlabeln(BW, conn);(2)Compute the area of each component. S = regionprops(L, 'Area');(3)Remove small objects. bw2 = ismember(L, find([S.Area] 阅读全文
