Paper Abstract

Two methods of extracting the region of a car number plate using parameter restricted Hough transformation[PRH] and that of hierarchical parameter restricted Hough transformation[HPRH] were proposed(1). The computational time and storage requirement are reduced by these methods. In the present report, an adaptive parameter restricted Hough transformation[APRH] is proposed. The APRH algorithm, in which the range of the parameter plane is adaptively restricted, gives higher performance than the previous two methods. As an example of application of this method, extraction of car number plate and its results are described.
