TitreImage Retrieval with non-regular pyramid partitioning via Graph-Cuts 
RésuméWe presents a nouvel approach to addresses the well-known problem of adding spatial information to the standard bag-of-visual-words (BoVW) model. To that end, a set of graphs descriptors are constructed for the entire image or for local image regions via graph-cuts based methods. These descriptors are then incorporated into a bag-of-visual-words approach, leading to a method called bag-of-bag-of-visual-words (BBoVW). In experimental results for Caltech101 benchmark, our proposed method performs better than SPM(Spatial Pyramid Matching) for 19 objects categories.
