击中击不中变换Matlab实现 MATLAB

matlab击中击不中函数为bwhitmiss，调用形式为：
【击中击不中变换Matlab实现】

Ihm = bwhitmiss(I, S1, S2); % I为输入图像 % S1、S2为结构元素

The syntax bwhitmiss(BW1,SE1,SE2) is equivalent to imerode(BW1,SE1) & imerode(~BW1,SE2)

更为直观的实现方式代码：

clear all; I = zeros(120,180); I(11:80,16:75) = 1; I(56:105,86:135) = 1; I(26:55,141:170) = 1; figure,imshow(I); se = zeros(58,58); se(5:54,5:54) = 1; figure,imshow(se); %击中击不中变换 Ie1 = imerode(I,se); figure,imshow(Ie1); Ic = 1 - I; figure,imshow(Ic); S2 = 1 - se; figure; imshow(S2); Ie2 = imerode(Ic,S2); figure,imshow(Ie2); Ihm = Ie1 & Ie2; figure,imshow(Ihm);
