Hey Everyone ! I am working on a project (named :Shadow based renal stone detection ) in which after applying region growing to detect stone (as most brighter part in the image)I have to verify the shadow under the stone with gray values( of shadow )ranging between 10 to 40 .How may I complete my task ? Screenshot along with this question may provide more clarity to my question. Any assistance regarding this matter will be highly appreciated.

Doctors say : in an ultrasound image of kidney containing stone , mostly stone is the the brightest area in that image and to verify that brighter area to be an actual stone a shadow is always there below the stone because the stone stops light rays to pass through.
