Out of bound Error
Posted:

I get the following error and I am unsure how to fix it. I tried to edit the rows and cols but it seems not to work. Does anyone know a quick fix to this problem:
??? Attempted to access cyy(1,901); index out of bounds because size(cyy)=[700,900].
Error in ==> snake at 31 eterm(i,j) = (cyy(i,j)*cx(i,j)*cx(i,j) 2 *cxy(i,j)*cx(i,j)*cy(i,j) + cxx(i,j)*cy(i,j)*cy(i,j))/((1+cx(i,j)*cx(i,j) + cy(i,j)*cy(i,j))^1.5);
The following code is listed below: image = imread(image.jpg);
%parameters N = 100; smth = rgb2gray(image);
% Calculating size of image [row col] = size(image);
eline = smth; %eline is simply the image intensities
[grady,gradx] = gradient(double(smth));
eedge = 1 * sqrt ((gradx .* gradx + grady .* grady)); %eedge is measured by gradient in the image
m1 = [1 1]; m2 = [1;1]; m3 = [1 2 1]; m4 = [1;2;1]; m5 = [1 1;1 1];
cx = conv2(smth,m1,'same'); cy = conv2(smth,m2,'same'); cxx = conv2(smth,m3,'same'); cyy = conv2(smth,m4,'same'); cxy = conv2(smth,m5,'same');
for i = 1:row for j= 1:col1 % eterm as deined in Kass et al Snakes paper eterm(i,j) = (cyy(i,j)*cx(i,j)*cx(i,j) 2 *cxy(i,j)*cx(i,j)*cy(i,j) + cxx(i,j)*cy(i,j)*cy(i,j))/((1+cx(i,j)*cx(i,j) + cy(i,j)*cy(i,j))^1.5); end end
