Title: Toshiaki Yagasaki: Innovator in Document Imaging and Pattern Recognition

Introduction

Toshiaki Yagasaki is a prominent inventor based in Irvine, California. He has made significant contributions to the fields of document imaging and pattern recognition. With a total of 5 patents to his name, Yagasaki's work has advanced the way we interact with and retrieve information from document images.

Latest Patents

Yagasaki's latest patents include a method and apparatus for creating, indexing, and viewing abstracted document images. This innovative approach allows for the storage of document images and the creation of a retrieval index, enabling users to efficiently retrieve and display these images. The method employs rule-based block selection techniques to identify various regions within a document, such as title-type regions and text-type regions. This structural information is then utilized to create a word-based retrieval index, which can be used in conjunction with search queries. The documents can be displayed in either full image mode or a rapid browsing mode, where only an abstract structural view is shown.

Another notable patent focuses on a pattern recognition method and apparatus that offers multiple recognition modes. This technology selects the appropriate mode based on the characteristics of the unknown pattern being recognized. The apparatus includes a pattern recognizer that compares unknown patterns with known patterns, enhancing the accuracy of recognition. This innovation can be implemented in stand-alone devices or distributed across a local area network.
