FINE-GRAINED SKETCH-BASED IMAGE RETRIEVAL USING SPATIAL RELATIVE FEATURE OF IMAGES
摘要
Abstract
Fine-grained sketch-based image retrieval(FG-SBIR)aims to use hand-drawn sketches as queries sample to perform instance-level retrieval in image databases.Due to problems such as offset and distortion,it is difficult for sketches to align with real images in space.A new FG-SBIR method based on spatial relative attention(SRA)is proposed.The coordinate map was used to extract spatial-aware features,and the spatial relative relationship was extracted based on the relative self-attention module.At the same time,a contrastive loss NT-Xent was introduced to obtain stronger feature representation.Experiments on two public datasets show that the method outperforms several state-of-the-art FG-SBIR methods on retrieval accuracy.关键词
