Abstract (in Japanese) (See Japanese page) 
(in English) In this article, we propose a robust non-rigid surface registration method, which registers a surface model to given images and which evaluates the confidence of the registration. A target surface is divided into local clusters, and the statistics of their shapes are parametrically represented in the surface model. The method registers the model by inferring the values of the parameters. Assuming that the sparseness of outliers in a given image, the proposed method automatically detects the outliers and ignores them to robustly register the model. For this robust registration, we employ the L1-norm regularization. We constructed a liver surface model and evaluated the performance of the proposed method. Experimental result shows that our proposed method outperformed the previous method significantly in accuracy.
