Abstract

A computer vision system having improved means for characterizing the parameters of edge segments of an unknown object is disclosed. The unknown object is transformed by a digital camera into an image and transformed by a wavelet projection transform so as to decompose the unknown objects into their constituent multi-scale edge segment features and provide recognition of the unknown object by relating their constituent edge features to each other.
