Abstract (in Japanese) (See Japanese page) 
(in English) One of the main problems in multi-view geometry is determining an effective method of feature extraction to locate corresponding points between successive frames. Finding the corresponding points is important in order to satisfy the epipolar geometry between the successive frames. Although the ROBPCA-SIFT method can be used in noised endoscopic images, it cannot be applied to endoscopic images with excessive noise because the method introduces unacceptable error which exceeds the criterion. An ICA-based denoising method such as preprocessing should therefore be applied. Experimental results show that the ROBPCA-SIFT method with the ICA-based denoising algorithm applied as a preprocessing step is reliable and has good performance for feature extraction from endoscopic images with excessive noise.
