  • Extraction of information processing steel images and moving images taken by camera or video-camera. Processing of data of music sound data, acceleration data and infra-red censor. I use GA (genetic algorithm) inspired by evolution of wild lives and NN(neural network) inspired by human or animal brains. I apply my work to measurement and improvement of human health, surveillance, watch and medical purpose.

  • 2D-3D GA Matching between CT and Roentgen Imaging of Scapula Focusing on Acromion and Angulus Inferior

    Shigeyoshi Nakajima , Mitsuhiko Ikebuchi

    ICIC Express Letters, Part B: Applications  11 ( 1 ) 75 - 84 2020.01  [Refereed]

     View Summary

    A dynamic 3D motion analysis of bones in vivo is one of very interested themes. We used GA(genetic algorithm) for 2D-3D matching of 3D position and rotation of a scapula and a 2D contour of a scapula in a Roentgen image as a previous research. The name of our software is GANESHA (Genetic Algorithm with Numeric Engine for SHoulder Ability). In the work our system search 6DOF of a scapula. But a search in 6-dimension space is very difficult. We here propose a method to search 2 DOF with fixed 4 (= 2×2)DOF. 4 DOF are calculated from 2D positions of an acromion and an angulus inferior which are observed with stability in Roentgen images and are pointed by user operations. It is easier for users to search in 2D space than to search in 6D space.
