Abstract

This paper describes a complete framework for the quantitative quality control of biological objects using computer vision. The techniques are described in the context of BCC-2, the second generation Beef Carcass Classification centre, which has operated as a prototype since March 1995. Installed in the slaughterline, BCC-2 analyses one half, dehided carcass, BCC-2 determines the visual properties: conformation, fatness and fat colour as well as objective quantities such as the percent of saleable meat and the cross sectional area of the rib eye. BCC-2 measures geometry and colour quantitatively. A procedure for maintaining the same calibration over time for several BCC-2 units has been developed. BCC-2 is built from a few inexpensive components. A frame thatpositions the half carcass in the slaughterline, a camera, two PC's, and a terminal. In addition, two slide projectors project stripes of light onto the carcass at an angle to the camera to provide informationabout the three-dimensional shape. The biological variation of the carcasses requires the use of advanced information processing techniques. traditional pattern recognition, principal component analysis, and neural networks. BCC-2 is adaptive, i.e. it is trained by examples, andBCC-2 is robust in the sense that it classifies all carcasses except the ones most damaged in the slaughter process.
