Paper Abstract

We present a critical review of the representation available for model-based object recognition. The choice of representation has a direct impact on the ability of the system to match objects, particularly in environments where noise or occlusion are presented. This review provides a set of criteria for object representation in recognition systems and this forms the basis upon which a qualitative critical review has been formulated. Initially well established techniques for object representation are reviewed. In particular object centered representations and viewer centered representations are addressed. The primary issue which afflicts these representations is the domain of objects which they can effectively represent. Free-form representations, which overcome this problem, are also examined. In particular, parametric representations including splines, implicit algebraic surfaces and finite element techniques, and geometric models which are based on differential geometry are considered. Ultimately, only representations, which possess an elegant blend of efficiency, accuracy and large representational domain are successful in providing a recognition system with the information required to achieve the level of scene understanding required in modern computer vision.
