Hi, I want to scan an image row-wise and store the index value of the concerned pixels (Ones with lowest grey values) in a matrix (note:There can be more than one pixel with such values). Currently I can scan a row at a time and it returns index of the first pixel which has lowest intensity value. Image size is 478 by 680. AND I am getting wrong index values.
I = imread('5.bmp');
I = im2gray(I);
imshow (I);
i=1:1:478;
[min_intensity,idx]= min(I(i,:));
idx = idx;
