Image-text Retrieval via Preserving Main Semantics of Vision
This addresses the challenge of cross-modal retrieval for AI systems by improving accuracy, though it is incremental as it builds on existing mapping approaches.
The paper tackles the problem of false matches in image-text retrieval caused by redundant secondary information in images by introducing a Visual Semantic Loss (VSL) to focus on main content, achieving superior performance on MSCOCO and Flickr30K datasets.
Image-text retrieval is one of the major tasks of cross-modal retrieval. Several approaches for this task map images and texts into a common space to create correspondences between the two modalities. However, due to the content (semantics) richness of an image, redundant secondary information in an image may cause false matches. To address this issue, this paper presents a semantic optimization approach, implemented as a Visual Semantic Loss (VSL), to assist the model in focusing on an image's main content. This approach is inspired by how people typically annotate the content of an image by describing its main content. Thus, we leverage the annotated texts corresponding to an image to assist the model in capturing the main content of the image, reducing the negative impact of secondary content. Extensive experiments on two benchmark datasets (MSCOCO and Flickr30K) demonstrate the superior performance of our method. The code is available at: https://github.com/ZhangXu0963/VSL.
