Paper Abstract

Using our recently modified curve-fitting-topological-coding (CFTC) computer program, we can automatically obtain a precise topological code to represent the topological property of a closely reconstructed boundary of a selected object in an edge-detected picture. This topological property is perhaps the most important property to be used for object identification. It is very accurate, yet very robust, because the topological property is independent of geometrical location, shape, size, orientation, and viewing angles. It is very accurate if two different objects to be differentiated or to be identified have different boundary topologies. Patch noise and obscuring noise can also be automatically eliminated as shown in some live experiments.
