Abstract

Large-scale content-based image retrieval is a challenge problem in computer vision. In this talk, I will present some recent works on image retrieval. We model the retrieval as a measure similarity in high dimensional semantic space. A real world retrieval task usually contains requirements from many aspects. To embed both appearance and semantic similarity in retrieval, we propose to learn the binary code which encodes identity and semantic attributes simultaneously. The basic idea is combined with both handcraft feature and CNN-learned feature. Different combination of training and code generations are compared. Extensive experiments are conducted on both face and general image sets. The results on these datasets show the promising performance.
