| Abstract(in English) | In this paper, we propose a method to detect scene changes from two images captured the same location at different times and under different capturing conditions by car mounted cameras. In our method, this comparison between two images can be achieved by a two-stage matching algorithm. In the first stage, SIFT keypoints are utilized to obtain the fundamental matrix from the images. Then, in the second stage, a SIFT feature-based dense region matching algorithm (i.e., Graph-cuts) with the epipolar geometry efficiently detects changed regions between the two images. Comparing with a naive SIFT feature-based dense matching and SIFT Flow, our method can result better performance in terms of both computational cost and matching accuracy for images captured by car mounted cameras. The effectiveness is evaluated with a large set of images captured by the car-mounted cameras in real environments. |
