Title: Innovations of Tatsuhiko Hirai
Introduction
Tatsuhiko Hirai is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of image processing, holding a total of 4 patents. His work focuses on enhancing security measures in printed documents through innovative technologies.
Latest Patents
Hirai's latest patents include an image processing apparatus and its method. This invention addresses the challenge of changing security levels in printed documents. When vector data is generated from a printed document, it typically reflects a low security level. This allows for editing and reprinting of the document. The process involves reading a document image, segmenting it into regions with different attributes, and extracting pointer information embedded in each region. The user can then convert specific image regions into vector data, which is registered with a security level in a server.
Another patent by Hirai focuses on storing a history of printed information, including dates and user details. This allows for searching stored information in case of data leaks. The system requires user authorization to access image data, which is then segmented into regions by block selection. Each segment is converted into vector data, and the system checks for matching objects in an image storage server. If a match is found, the corresponding object ID is retrieved. If not, a new object ID is generated and registered.
