Hi all,
I segmented a MRI image having brain tumor by region growing. After region growing,the tumor gets segmented in the MRI image. But I am not able to separate it and show only the tumor part.Pls suggest the coding steps. I had attached my code and the corresponding input MRI image. Pls suggest the steps.
my code:
img1=regiongrowing(double(L),119,58,50);
figure,imshow(img1);

请先登录，再回答此问题。

After regiongrowing you probably have a binary image - essentially a mask. So you can just use that to set other parts of the image to zero:
maskedImage = grayImage; % Initialize.
maskedImage(~mask) = 0; % Zero out areas not in tumor mask.
