Recognizing partially visible 2-D non-rigid wire-shapes

Abstract

A technique for the fast recognition of partially visible 2-D non- rigid wire-shapes is presented. For this, the skeleton of an object is first decomposed into a set of parts called fundamental parts (FPs). Each FP is next described by a code composed of five integer numbers. The code of each FP is then used to build the corresponding database of models. During a second phase (of indexing), the FPs extracted from a test image are used to index the model database subtracting from it the list of objects possibly present in the image. The performance of the system is tested with a set of insect designs.
