Conventional image recognition methods usually include dividing the keypoint neighborhood (for local features) or the whole object (for global features) into a grid of blocks, computing the gradient magnitude and orientation at each image sample point and uniting the orientation histograms of all blocks into a single descriptor. The query image is recognized by matching ...

The insufficient performance of statistical recognition of composite objects (images, speech signals) is explored in case of medium-sized database (thousands of classes). In contrast to heuristic approximate nearest-neighbor methods we propose a statistically optimal greedy algorithm. The decision is made based on the Kullback-Leibler minimum information discrimination principle. The model object to be checked at ...
