Hi guys,

Basically I've segmented ROI's from my image, and I now want to overlay the perimeter of these ROI's on the original image, but I am having difficulty in doing so. Anyone know how I might go about doing this?

 

Have you seen the matlab pendulum tracking example? They define a region-of-interest, crop it, then process it.

They also do some overlaying of lines, etc.

Ok, new problem . I'm trying to modify example 2 , from here, to work with my own 1024 X 1024 image. However I run into difficulties in the last few lines :

mask = repmat(mask,[1,1,3]);
masked_image = zeros(m,n,3,'uint8');
masked_image(mask) = I(mask);

I get the "Index exceeds matrix dimensions" error.

I assume its something in these three lines that has to change?
Thanks.
