Right now I can detect coloured objects and place a square box around the detected object (As seen in the image below). However, it automatically places a square box around all objects but what I wanted to do is to place square box around square objects and place a circle box around circle objects. I've been trying figure out how to do this a couple days with no luck. Please help
The image is from a live video capture from webcam
I'm using a modified version of this code from http://au.mathworks.com/matlabcentral/fileexchange/28757-tracking-red-color-objects-using-matlab

First detect the colored objects (see my File Exchange for color segmentation demos). Then you'll have a segmented image (binary mask image) and you can call bwboundaries() to plot the exact shape around them.
I also attach my shape recognition demo in case you want to check that out.

I did - it's in the File Exchange. You can get it there so why do I need to attach it here?
