matlab：檢測從骨架更好的分支點

Question

我有兩個骨架圖像，我提取的分支點。不幸的是，分支似乎並不正確。有沒有人有關於如何提取有效分支點（即「y」形狀點）的建議？

reg1 = imread('region1.tif'); 
[i,j] = ind2sub(size(reg1), find(bwmorph(reg1,'branchpoint') == 1)); 
h=figure; imshow(reg1); hold on; plot(j,i,'rx');print(h,'reg1overlay','-dtiff'); 

在第一示例下面只應有一個分支點：

reg2 = imread('region2.tif'); 
[i,j] = ind2sub(size(reg2), find(bwmorph(reg2,'branchpoint') == 1)); 
h=figure; imshow(reg2); hold on; plot(j,i,'rx');print(h,'reg2overlay','-dtiff'); 

在第二個例子下面只應有沒有分支點：

Answer 1

嘗試：

branchskel = bwmorph(BW,'skel',Inf); %BW is your binarized image 
branchskel = bwmorph(branchskel,'thin'); %this should remove those pixel piles that are giving you problems 
B = bwmorph(branchskel, 'branchpoints'); 
[yb,xb] = find(B);
