图像分割

点，线和边缘检测　

点检测

>> w = [-1 -1 -1; -1 8 -1; -1 -1 -1];
>> f = imread('Fig1002(a)(test_pattern_with_single_pixel).tif');
>> g = abs(imfilter(double(f),w));
>> T = max(g(:));
>> g = g >= T;
>> imshow(f);figure,imshow(g);

（我看不清成果…）

线检测

>> w = [2 -1 -1; -1 2 -1;-1 -1 2];
>> f = imread('Fig1004(a)(wirebond_mask).tif');
>> imshow(f);
>> g = imfilter(double(f),w);
>> figure,imshow(g,[]
