Scalable Image Retrieval by Sparse Product Quantization

15 Mar 2016Qingqun NingJianke ZhuZhiyuan ZhongSteven C. H. HoiChun Chen

Fast Approximate Nearest Neighbor (ANN) search technique for high-dimensional feature indexing and retrieval is the crux of large-scale image retrieval. A recent promising technique is Product Quantization, which attempts to index high-dimensional image features by decomposing the feature space into a Cartesian product of low dimensional subspaces and quantizing each of them separately...
