I wrote the following code to plot the maximum intensity value in an Infrared image.It had shaded of white and black so I have thresholded it.But I don't find the output to be accurate.Can anyone help me out in correcting the code.
function [row col] = maximum( X )
[r c] = size(X);
for i=1:r
for j=1:c
if X(i,j)>140 && X(i,j)<160
temp(i,j) = X(i,j);
else
temp(i,j) = 1;
end
if temp(i,j) == max(max(temp))
row = i;
col = j;
end
end
end
end
x0 = rgb2gray(imread('img_1.jpg'));
x1 = rgb2gray(imread('img_2.jpg'));
[row0 col0] = maximum(x0);
[row1 col1] = maximum(x1);
figure(1)
plot(row0,col0,'+',row1,col1,'d')
Any help will be appreciated.
