Region Growing segmentation not giving proper result.
显示 更早的评论
Hi,
I am applying the region growing algorithm to segment tumors in breast images. I is the original image. The brightest spot in the center should be the tumor. The segmentation should only display that spot. However, after applying the algorthm, the resultant image is that of I1 which is not accurate. Any suggestions would be appreciated.
I = im2double(imread('I.jpg'));
figure,imshow(I)
x=198; y=359;
J = regiongrowing(I,x,y,0.5);
figure, imshow(I+J);

Hi Warid,
I have reproduces your code, I have made just small adjustments. The new code is like that:
I = im2double(imread('I.jpg'));
x=463; y=311; %changed the starting point to this.
J = regiongrowing(I,x,y,0.04); %decreased the threshold to 0.04
figure, imshow(I+J);
My figure after this code is below here:
Hope this Helps!

@Ahamed Mansoor why is it not supported? What indicates that to you? Are you missing a toolbox?
