Abstract

Patch-based methods, which constitute the state of the art in object recognition, are often applied to video data, where motion information provides a valuable clue for separating objects of interest from the background. We show that such motion-based segmentation improves the robustness of patch-based recognition with respect to clutter. Our approach ­ which employs segmentation information to rule out incorrect correspondences between training and test views ­ is demonstrated to distinctly outperform baselines operating on unsegmented images. Relative improvements reach 50% for the recognition of specific objects, and 33% for object category retrieval.
