    Spinal deformity detection based on Fourier descriptor from moire images  [in Japanese]

    TANOUE Toyoaki , KIM Hyoungseop , TAN Joo Kooi , ISHIKAWA Seiji , SHINOMIYA Takashi

    … In order to detect the spinal deformity in early stage, orthopedists have traditionally performed a painless examination called a forward bending test or moire topographic image test in mass screening of school. … It is, however, inspection base on the forward bending method takes much time, and the moire images and visual examination also require a large amount of moire images because from elementary as well as junior high schools are collected. …

    An Automatic Classification Method for Spinal Deformity Employing Statistical Features of Gray Values from the Moire Topographic Images  [in Japanese]

    Nakano Satoshi , Kim Hyoungseop , Tan Joo Kooi , Ishikawa Seiji , Otsuka Yoshinori , Shimizu Hisashi , Shinomiya Takashi

    … In this paper, we propose a new automatic classification method for spinal deformity from moire topographic images which obtained asymmetric degree by using a new statistical feature. … In our method, we detect three features such as mean values, standard deviation from an original moire image and cross correlation value from a converted low resolution image. …

    Automatic Spinal Deformity Detection Employing AdaBoost

    NAKANO Satoshi , KIM Hyoungseop , ISHIKAWA Seiji , OTSUKA Yoshinori , SHIMIZU Hisashi , SHINOMIYA Takashi

    … To solve this problem, a moire method has been proposed which takes moire topographic images of human subject backs and checks symmetry/asymmetry of the moire patterns in a two-dimensional way. … In this paper, we propose a new method for automatic detection of spinal deformity from moire topographic images. …
