Analysis of Hough data behavior for scene recognition

In this paper, the authors describe on an analysis of Hough data behavior for recognition of three dimensional scene. First, the relation between the change of shooting conditions and the behavior of Hough data was investigated, using the perspective transformation of lines. The investigation result cleared that the behavior shows a characteristic pattern and keeps three dimensional information of lines. Next, a work on a scene image verification is explained. In the study, we describe on Hough data verification using matched filter. In this paper, the behavior of Hough data is explained in detail and a test of the scene image verification is shown.
