Abstract

This paper presents a real-time classification algorithm for 2D object contours using a multi-resolution tree model which is implemented in a modular VLSI architecture. The hardware implementation takes advantage of pipelining, parallelism, and the speed of VLSI technology to perform real-time object classification. Using the multi-resolution tree model, the classification algorithm is invariant under 2D similarity transformations and recognizes the visible portions of occluded objects. The VLSI classification system is implemented in 0.8 /spl mu/m CMOS and is capable of performing 34000 matchings per second.
