In this paper, we propose a hierarchical probabilistic model for scene classification. This model infers the local–class–shared and local–class-specific latent topics respectively. Our approach consists of first learning the latent topics from the BoW representation and subsequently, training SVM on the distribution of the latent topics. This approach is(More)
The superpixel extraction algorithm is becoming increasingly significant for pattern recognition applications. Different superpixel generation methods have different properties and lead to various over-segmentation results. In this paper, we treat the over-segmentation as an image decomposition problem, and propose a novel discriminative sparse coding (DSC)(More)
