Paper Abstract

An algorithm for fmding characters from complicated document image is presented. We assume that all characters appear in strings which contain at least two characters. Characters overlapped by illustration characters touched by illustration or other characters and characters divided into fragments can be found. In the first step initial character probabilities are attached to pixels. In the second step they are updated by neighboring character probabilities by relaxation method. This algorithm is shown to be faster than the simple template matching algorithm for the typical document. An application to the system that automatically makes the data for electronic catalogue of automotive parts from immage is introduced.
