Title: Innovations of Mitsutoshi Arai
Introduction
Mitsutoshi Arai is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of image processing and encoding. With a total of 5 patents, Arai's work focuses on enhancing the efficiency of pattern matching and coding methods.
Latest Patents
One of Arai's latest patents is a method and apparatus for pattern matching encoding. This invention includes a pattern extracting unit that extracts patterns from input binary or multi-level image data. It also features an accumulating/match-checking unit that accumulates each extracted pattern and executes a match-check with previously accumulated patterns. Additionally, a line segment checking unit evaluates each pixel in the match pattern or extracted pattern to determine its position on various line segments. Finally, an encoding unit encodes the extracted pattern by selecting an optimal template based on the results of the line segment checking. This innovation reduces the codes in pattern matching encoding, thereby improving the efficiency of code transmission and accumulation.
Another notable patent by Arai is a coding method and coder using pattern matching. This invention includes a dot angle conversion unit that converts the dot angle of image data into either 0 degrees or 45 degrees. An in-mark correlation checking unit determines the dot frequency of the converted image data. A mark re-dividing unit generates small-sized marks based on this frequency. The match determination unit checks if a library contains a mark that matches the extracted mark. If a match is found, both the extracted mark and the matching mark are output to a match template processing unit.
