Title
Boosted random contextual semantic space based representation for visual recognition.
Abstract
We propose an image representation method using boosted random contextual semantic spaces.The proposed BRCSS can alleviate the semantic gap by using semantic space based image representation.BRCSS uses the visual representation of images in an iterative way with random sampling and re-weighting.Experimental results demonstrate the effectiveness and efficiency of the proposed method. Visual information has been widely used for image representation. Although proven very effective, the visual representation lacks explicit semantics. However, how to generate a proper semantic space for image representation is still an open problem that needs to be solved. To jointly model the visual and semantic representations of images, we propose a boosted random contextual semantic space based image representation method. Images are initially represented using local feature's distribution histograms. The semantic space is generated by randomly selecting training images. Images are then mapped into the semantic space accordingly. Semantic context is explored to model the correlations of different semantics which is then used for classification. The classification results are used to re-weight training images in a boosted way. The re-weighted images are used to construct new semantic space for classification. In this way, we are able to jointly consider the visual and semantic information of images. Image classification experiments on several public datasets show the effectiveness of the proposed method.
