Advancing Visual Grounding With Scene Knowledge: Benchmark and Method

CVPR 2023poster

Visual grounding (VG) aims to establish fine-grained alignment between vision and language. Ideally, it can be a testbed for vision-and-language models to evaluate their understanding of the images and texts and their reasoning abilities over their joint space. However, most existing VG datasets are…
