Abstract / Description of output

The key challenge for learning a fine-grained sketch-based image retrieval (FG-SBIR) model is to bridge the domain gap between photo and sketch. Existing models learn a deep joint embedding space with discriminative losses where a photo and a sketch can be compared. In this paper, we propose a novel discriminative-generative hybrid model by introducing a generative task of cross-domain image synthesis. This task enforces the learned embedding space to preserve all the domain invariant information that is useful for cross-domain reconstruction, thus explicitly reducing the domain gap as opposed to existing models. Extensive experiments on the largest FG-SBIR dataset Sketchy [19] show that the proposed model significantly outperforms state-of-the-art discriminative FG-SBIR models.
