Researchers from Sichuan University introduce D2S-VSE, a two-stage framework for image-text matching that enhances visual and sparse text embedding information capacity via dense-to-sparse feature distillation. This method yields superior performance, boosting Recall@1 for text retrieval on Flickr30K by 6.8% compared to prior methods.
Key insights
- The information capacity of visual semantic embeddings is a critical factor for successful image-text matching, enabling better capture of features and robustness against ambiguous samples.
- Dense textual descriptions, especially those generated by large multimodal models, can significantly enrich the information capacity of visual embeddings during pre-training.
- A dense-to-sparse feature distillation mechanism effectively transfers enhanced information capacity to sparse text embeddings, aligning modalities while maintaining efficiency during inference.
