The ticket has been solved. You can use it by Blob.getConvexityDefects(). You can download simplecv from github. and do check the docs by Blob.getConvexityDefects?

We don't currently have a convexity defect feature in the Blob class but I could see where it would be a nice feature to have. I went ahead and filed a ticket for it. There is a good example of how to do it in the ticket. If I get some spare time I will give it a shot. If you want to try to do it yourself let us know and we will provide as much support as we can and merge it into develop. Here is the example. The method probably should live in the BlobMaker class.
