DViN: Dynamic Visual Routing Network for Weakly Supervised Referring Expression Comprehension

CVPR 2025poster

In this paper, we focus on weakly supervised referring expression comprehension (REC), and identify that the lack of fine-grained visual capability greatly limits the upper performance bound of existing methods. To address this issue, we propose a novel framework for weakly supervised REC, namely Dy…

SPECS: Specificity-Enhanced CLIP-Score for Long Image Caption Evaluation

EMNLP 2025

As interest grows in generating long, detailed image captions, standard evaluation metrics become increasingly unreliable. N-gram-based metrics though efficient, fail to capture semantic correctness. Representational Similarity (RS) metrics, designed to address this, initially saw limited use due to

APL: Anchor-based Prompt Learning for One-stage Weakly Supervised Referring Expression Comprehension

ECCV 2024poster

"Referring Expression Comprehension (REC) aims to ground the target object based on a given referring expression, which requires expensive instance-level annotations for training. To address this issue, recent advances explore an efficient one-stage weakly supervised REC model called RefCLIP. Partic…
