Abstract :
In this paper, we report a new Generalized Hough Transform (GHT) for the recognition of non-analytic objects. Our proposed GHT algorithm is able to replace the conventional 4-D Hough space with a 2-D one. The significant reduction of memory requirement leads to a great simplification of the peak searching time for the recognition. By an analysis of the angular deviation of the edge operator, we also derive a new profile for the modeling of peaks, which is extremely helpful for our peak searching and verification processes
