Description	Repeated structures such as building facades, fences or road markings often represent a significant challenge for place recognition. Repeated structures are notoriously hard fo restablishing correspondences using multi-view geometry. Even more importantly, they violate the feature independence assumed in the bag-of-visual-words representation which often leads to over-counting evidence and significant degradation of retrieval performance. In this work we show that repeated structures are not a nuisance but, when appropriately represented, they fo rm an important distinguishing feature for many places. We describe a representation of repeat ed structures suitable for scalable retrieval. It is based on robust detection of repeated ima ge structures and a simple modification of weights in the bag-of-visual-word model. Place reco gnition results are shown on datasets of street-level imagery from Pittsburgh and San Francisc o demonstrating significant gains in recognition performance compared to the standard bag-of-v isual-words baseline and more recently proposed burstiness weighting.
