Comparative research on compression algorithms of bag-of-features
Against the problem that compression algorithms for bag-of-features(BoF) ignore the spatial relationships of coded vectors
we propose a fusing algorithm of compression algorithms and spatial pyramid model in this paper. Meanwhile
we carried out a set of comparative experiments on several public image datasets. The experimental results show that compression algorithms are robust to visual word numbers and pooling methods of coded vectors. Otherwise
compression algorithms based on subspace methods have achieved best classification performances in the high-level feature space
and best accuracies and smallest time cost in multiple image datasets.
