I have a label matrix. I am using regionprops to measure properties for each labeled region. Some of those properties are images (e.g. FilledImage, Image, ConvexImage), but they are always the size of the bounding box of the region. How can I convert this to the size of the original image?
Example
Suppose
L = [2 2 0 0 0 0;
2 2 0 1 1 0;
0 0 0 0 1 0;
0 0 1 1 1 0];
stats = regionprops(L,'all');
Then
stats(1).ConvexImage = [0 1 1;
0 1 1;
1 1 1];
But what I want is
[0 0 0 0 0 0;
0 0 0 1 1 0;
0 0 0 1 1 0;
0 0 1 1 1 0];
How can I achieve this?
I'm sure it can be done by using the BoundingBox, but for some reason, I cannot recall how to do this.
