Abstract Geometric hashing is an object recognition method using arrangements of feature points. This method is a robust retrieval method against geometric transformations by examining all of possible coordinate systems. We use the geometric hashing to recognize characters undergone affine transformation. However, the more feature points are, the more coordinate systems are. Thus computational cost of recognizing characters is large. We propose a method to reduce the computational cost by restricting possible coordinate systems. By experiments, we confirmed that the proposed method can recognize characters faster.
