I checked the attached image: It is not 1600 * 1200
>> I=imread('image2-1.jpg');
>> size(I)
ans =
385 513 3
I resized the image just in case if attaced image is wrong:
I = imresize(I, [1600 1200], 'bilinear');
>> size(I)
ans =
1600 1200 3
Your d-value in the while loop has to be at the end of the inner while loop:
while c <= 1600
d = 1;
while d <= 1200
I3(c, d) = BW1(c, d);
if BW1(c,d)>0
I(c,d,1)=127;
I(c,d,2)=127;
I(c,d,3)=127;
end
d = d+1;
end
c = c+1;
end
But I found few problems in the code..
>> max(BW1(:))
ans =
logical
0
so, there are no values in the BW1 so your ' if condition' is never true and 'I' values doesn't get updated.
check your code where you are computing BW1 where you are expecting to find the marked regions
