Abstract

This paper proposes a new algorithm for detecting character strings in an image containing illustrations and characters. It also describes a part number entry system that utilizes this algorithm. The algorithm detects character strings by investigating the horizontal boundaries of rectangles representing characters strings. It can be performed a high speed, and can detect characters touching an illustration. Using this algorithm, the part number entry system extracts areas of part numbers scattered among illustrations and then recognizes the. This is a software program implemented on a personal computer, and is composed of four subprograms: detection of character strings, character recognition, post-processing, and flexible user-interface for error correction.
