Latest Patents

Katsumata's latest patents include a corresponding point searching method and a three-dimensional position measuring method. The corresponding point searching method involves capturing multiple images of an object from different viewpoints. One image is designated as the standard image, while another serves as the reference image. By cutting one-dimensional pixel data strings from both images along calculated epipolar lines, a phase-only correlation function is computed to determine the correlation peak position. This allows for the identification of a corresponding point based on positional shifts. His iris authentication apparatus includes an iris area extraction unit, a registration pattern generating unit, a collation pattern generating unit, and a collation unit. This apparatus effectively extracts and collates iris patterns from sensed images, enhancing biometric security.
