Abstract

Computer vision systems have varied applications and often the first goal of a vision system is the recognition of 3-D rigid objects. Model-based recognition systems rely upon a model to represent an object both tersely and uniquely to allow for efficient matching. The View Signature II (VSII) representation is a viewer-centred modelling scheme. The VSII representation requires one VSII view signature to represent a single view of an object and is invariant to rotation about the z axis. This is achieved by constructing a linear string of alpha-numeric characters from circular strings representing different concentric levels in a view of an object. A view signature is an ordered list of junction and level signatures and can be considered a string for matching purposes. Junction signatures represent the cotermination of edges and contours with their respective adjacent surfaces. A feature of view signature construction is the uniform processing of both the stored model and matching input, thereby removing the possibility of incompatibility between model and input. The motivation for the View Signature representation, its syntax and a technique for modelling 3-D rigid objects is described.
