WebIn SIFT-BOW, pooling is performed by encoding SIFTs from nearby scales using the quantized visual dictionary, while DSP-SIFT combines the histograms of gradient orientations across scales directly. To compute similarity between SIFT-BOWs, we tested both the intersection kernel and ℓ 1 norm, and achieved a best performance with the latter …
