here i attached the picture and the code as well. 'stomachgray.tif' is grayscale image
a = imread ('stomachgray.tif');
b = imcrop (a);
mask = zeros(size(b));
mask(100:end-100,100:end-100) = 1;
bw = activecontour(b,mask,1000);
c = im2double(bw); shading flat
d = imgaussfilt3 (c,4);
colormap(copper)
mesh(d.*100)
