<p>In the grading of shell eggs passing in a stream through a candling bed, images of the eggs are compared with image data characteristic of eggs of known grade so as to assign a grade to each egg in the stream. Positional information representative of the movement of the eggs is combined with the assigned grade to control a mechanical egg routing device. Images of multiple egg streams may be multiplexed and processed together. The images may be Fourier transformed before comparison.</p> |
