Title: Shunji Mori: Innovator in Optical Character Recognition

Introduction

Shunji Mori is a notable inventor based in Kashiwa, Japan. He has made significant contributions to the field of optical character recognition, holding a total of 3 patents. His work focuses on developing systems that enhance the recognition of visual patterns, particularly in handprinted characters.

Latest Patents

One of his latest patents is a "Pattern Reading System." This apparatus recognizes visual patterns of handprinted characters using an optical character reader. It employs an outermost point method to read patterns by tracing the contour stored in a two-dimensional memory. The system simultaneously obtains distances from the starting point and integrated values of the coordinates of the traced points. This allows for the segmentation of contours into convex line segments, concavity line segments, and hole segments. The system also rejects shorter convex line segments and matches the remaining segments against a pre-prepared dictionary to determine the pattern's identity.

Another significant patent is the "Feature Extraction System for Digitized Character Information." This method extracts necessary character features for recognition from digitized character information detected by an optical scanner. It integrates local features from adjacent rows or columns of a digitized character pattern, extracting global features such as concavity, convexity, loop, and connectivity. The method also separates global feature regions and codes each segment without losing information, while eliminating local noise during the extraction process.
