Using densely recorded scenes for place recognition
We investigate the task of efficiently modeling a scene to build a robust place recognition system. We propose an approach which involves densely capturing a place with video recordings to greedily cover as many viewpoints of the place as possible. Our contribution is a framework to (1) effectively exploit the temporal continuity intrinsic in the video sequences to reduce the amount of data to process without losing the unique visual information which describes a place, and (2) train discriminative classifiers with the reduced data for place recognition. We show that our method is more efficient and effective than straightforwardly applying scene or object category recognition methods on the video frames.
