| 英文摘要 | spatial pyramid matching is a standard architecture for categorical image retrieval. however, its performance is largely limited by the prespecified rectangular spatial regions when pooling local descriptors. in this paper, we propose to learn object-shaped and directional receptive fields for image categorization. in particular, different objects in an image are seamlessly constructed by superpixels, while the direction captures human gaze shifting path. by generating a number of superpixels in each image, we construct graphlets to describe different objects. they function as the object-shaped receptive fields for image comparison. due to the huge number of graphlets in an image, a saliency-guided graphlet selection algorithm is proposed. a manifold embedding algorithm encodes graphlets with the semantics of training image tags. then, we derive a manifold propagation to calculate the postembedding graphlets by leveraging visual saliency maps. the sequentially propagated graphlets constitute a path that mimics human gaze shifting. finally, we use the learned graphlet path as receptive fields for local image descriptor pooling. the local descriptors from similar receptive fields of pairwise images more significantly contribute to the final image kernel. thorough experiments demonstrate the advantage of our approach. |
