Automatic Registration of Phalanges Regions in CR Images Based on Scale-Invariant Salient Region Features
説明
As two common orthopedic diseases, there are rheumatoid arthritis (RA) and osteoporosis. And early detection and early treatment are important for these diseases. However, some problem such as mass screening on data sets, mis-diagnosis are still remained in visual screening. In order to solve these problems and reduce the burden to physicians, needs of an automatic diagnosis system capable of performing quantitative analysis is anticipated. In this paper, we carry out the development of a registration method of phalanges regions from CR images of the hand to detect temporal changes of phalanges regions by alignment between previous image and current one. The proposed method is carried out registration of phalanges regions using salient region features (SRF) in image. Specifically, SRF are detected from phalanges regions. Then, rigid registration technique is performed using deformation amount based on SRF. We applied our method on 84 pairs of CR temporal images of phalanges regions.
