Bag-of-Features (BOF) and Spatial Pyramid Matching (SPM) representation have become well-established in image classification and retrieval, owing to its simplicity and good performance. However, the hyper dimensionality of BOF vectors always faces the difficulty of “curse of dimensionality”, and leads to huge computation and storage complexity. To create a compact and discriminative BOF representations,...
Context plays a valuable role in any image understanding task confirmed by numerous studies which have shown the importance of contextual information in computer vision tasks, like object detection, scene classification and image retrieval. Studies of human perception on the tasks of scene classification and visual search have shown that human visual system makes extensive use of contextual information...
