A method for fast, computerized detection of bruises in magnetic resonance images (MRI) of apples was developed. It uses a simple thresholding technique combined with considerations of the apple geometry to distinguish between bright pixels representing the vascular system, and those representing bruises. The algorithm was tested on 20 images of ten Jonathan apples (before and after bruising), ten images of Golden Delicious apples and ten images of Hermon apples, and it demonstrated its ability to distinguish between bruised and non-bruised apples. This is the first step in the development of a sensing method using three-dimensional imaging and image analysis for detection of bruises.
