I have a grayscale image image named tumour.
I need to find the area where the intensity is greater than 0.
I have another variable outline showing the outline of original image.
G1 is an empty array.
To find it properly, I have used this code:
if((outline(i,j)>0) && sum(sum(tumor(i-5,j-5),tumor(i+5,j+5)))>0)
I want to get the outline of only the tumour.
However, I am getting this error (in the sum() part) and I am unable to solve it:
Error using sum
Dimension argument must be a positive integer scalar, a vector of unique positive integers, or 'all'.
