I am getting error
Attempted to access g(0,0); index must be a positive integer or logical.
Error in ==> Untitled6 at 19 g(y1,i) = 1;
can u please why i get thiserror
my code is
image=imread('door.jpg')
image=rgb2gray(image)
[image1 num] = bwlabel(image);
stats = regionprops(image1, 'BoundingBox');
g = image;
[M N] = size(stats);
for k = 1:M
for i = floor(stats(k).BoundingBox(1)):floor(stats(k).BoundingBox(1))+stats(k).BoundingBox(3)
for j = floor(stats(k).BoundingBox(2)):floor(stats(k).BoundingBox(2))+stats(k).BoundingBox(4)
x1 = floor(stats(k).BoundingBox(1));
y1 = floor(stats(k).BoundingBox(2));
g(y1,i) = 1;
g(y1+stats(k).BoundingBox(4),i) = 1;
g(j,x1) = 1;
g(j,x1+stats(k).BoundingBox(3)) = 1;
end
end
end

You need to ensure all of the indices are greater than 0. When you round things (using "floor") you must be encountering values in your "BoundingBox" that are between 0 and 0.5 - can you just add 1 to all your results, or use "ceil" instead?
