%segementation of cup using active counter(snakes)
I = imread('after opening 1.jpg');  %-- load the image
Error using imread>get_full_filename
File "after opening 1.jpg" does not exist.

Error in imread (line 372)
        fullname = get_full_filename(filename);
m = zeros(size(I,1),size(I,2));          %-- create initial mask
m(300:329,300:329) = 1;
I = imresize(I,.5);  %-- make image smaller 
m = imresize(m,.5);  %     for fast computation
subplot(2,2,1); imshow(I); title('Input Image');
subplot(2,2,2); imshow(m); title('Initialization');
subplot(2,2,3); title('Segmentation');
seg = region_seg(I, m,220); %-- Run segmentation
subplot(2,2,4);figure, imshow(seg); title('segemented cup');
imwrite(seg,'segemented cup 1.jpg')

I segmented the Cup region using an active counter (snake). Now I want to locate the segmented region on the original image as a perfect circular boundary. Could you assist in modifying the code to accomplish this?
