How can I detect broken circles in Matlab?

Hi

As a rookie in Matlab, I have a question; I need to detect and mark out only the broken M&M's on the uploaded picture. How do I do this? I have searched far and wide on the big internet, but I am still finding myself to be empty handed in the matter.

Thanks

Hi, you have to binarize the image with im2bw than you can use some function to be sure that all elements are non connected like imerode than you have to close contour and fill holes using imclose imfill

at this stage maybe a denoising step with bwareaopen is appreciable

and finally you cal extract all properties with regionprops

simply you can ceck the perimeter or the roundness of you m&m, maybe the minimum axes should be the solution if minimun axex< threshold is broken

Best.
