Matlab watershed函数学习(2)

%   2. Compute the distance transform of thecomplement of the binary

%      image.

%

%       D = bwdist(~bw);

%       figure,imshow(D,[],'InitialMagnification','fit')

%       title('Distance transform of ~bw')

2. 计算上述二值图像的补的距离变换

%   3. Complement the distance transform, andforce pixels that don't

%      belong to the objects to be at -Inf.

%

%       D = -D;

%       D(~bw) = -Inf;

3. 计算距离变换的补, 并令不属于两个对象的像素为负无穷.

%   4. Compute the watershed transform, anddisplay the resulting label

%      matrix as an RGB image.

%

%       L = watershed(D);

%       rgb = label2rgb(L,'jet',[.5 .5 .5]);

%       figure,imshow(rgb,'InitialMagnification','fit')
