我打算把圖片二質化後，把物體作連續膨脹8次(讓物體中間被填滿
再連續侵蝕8次(讓物體恢復原大小)，再抓出各物體其質心
可是此時發現一個問題物體跟物體間在膨脹時，可能會發生物體重疊狀況，
導致結果與預期不符合，我該如何改善呢?
以下是程式碼:
clear
A=imread('C:\Documents and Settings\Administrator\桌面\012.jpg');
level = graythresh(A);
K = im2bw(A,level); )
imshow(A)
figure,imshow(K)
se=strel('disk',3);
B=imclose(K,se);
figure, imshow(B)
imwrite(G,'C:\Documents and Settings\LAN\桌面\01_003.jpg')
sf=strel('disk',5);
Z=imerode(B,sf);
figure, imshow(Z)
Y=imerode(Z,sf);
figure, imshow(Y)
X=imerode(Y,sf);
figure, imshow(X)
W=imerode(X,sf);
figure, imshow(W)
V=imerode(W,sf);
figure, imshow(V)
S=imerode(V,sf);
figure, imshow(S)
T=imerode(S,sf);
figure, imshow(T)
U=imerode(T,sf);
figure, imshow(U)
C=imdilate(U,sf);
figure, imshow(C)
D=imdilate(C,sf);
figure, imshow(D)
E=imdilate(D,sf);
figure, imshow(E)
F=imdilate(E,sf);
figure, imshow(F)
G=imdilate(F,sf);
figure, imshow(G)
H=imdilate(G,sf);
figure, imshow(H)
I=imdilate(H,sf);
figure, imshow(I)
J=imdilate(I,sf);
figure, imshow(J)
sum=0;
for i=1:length(J(:,1))
for j=1:length(J(1,:))
if(J(i,j)==0)sum=sum 1;
end
end
end
n=sum
AB=imcomplement(J)
figure, imshow(AB)
imwrite(AB,'C:\Documents and Settings\Administrator\桌面\039.jpg')
[L, n] = bwlabel(AB)
imshow(AB)
hold on
for k=1:n
[r, c] = find(L == k);
rbar=mean(r);
cbar=mean(c);
plot(cbar, rbar, 'Marker', 'o', 'MarkerEdgeColor', 'k', 'MarkerFaceColor',
'k', 'MarkerSize', 10)
plot(cbar, rbar, 'Marker', '*', 'MarkerEdgeColor', 'w')
end
imwrite(AB,'C:\Documents and Settings\Administrator\桌面\040.jpg')

有聽說過分水嶺法
如果使用所謂的分水嶺法的話，有什麼要注意的嗎?
或是有更強大的方法呢?
