A CHIP-SET FOR THE GENERALIZED HOUGH TRANSFORM

This paper describes the architecture of a chip-set that can be adopte d in systems for object recognition based on the Generalized Hough Tra nsform (GHT). The targeted applications aim at the real-time localizat ion of two-dimensions objects of arbitrary shape not analytically desc ribed: this system has a throughput allowing for real-time operation o n standard television signals. The characteristics of the GHT recognit ion process, aimed at generic bi-dimensional shapes, have been careful ly exploited in order to map into silicon this transformation, so far considered too complex for a VLSI implementation. A functional descrip tion of the chip-set modules is given; the architectural aspects are a nalysed, together with the results of the prototyping phase, which add resses the problems of VLSI integration.
