ABSTRACT, A PC-based system with video camera and incandescent back lighting was used to generate images of a single, stationary egg. Processing algorithms were developed to accurately (a) isolate the ogg from the rest of the image, (b) enhance features of the Qgg shell, and (c) distinguish between shell cracks and noise. For a sample of 113 eggs, this system was able to correctly analyze an egg for the presence of a crack 96% of the time.
