Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we propose a method of recognizing block scenes from monocular images. Block-like objects are represented by 3-D object models. At each location in a scene, several promising models are generated. The fidelity of the object models to edges extracted from the images and the interrelations between the adjoining object models are evaluated by use of the Markov Random Field (MRF) model that is composed of the object models. The most likely state of the MRF model is obtained by minimizing its posteriori energy function with a primal-dual interior point method. The proposed method is applied to actual scenes including several block-like objects.
