Uncovering Prototypical Knowledge for Weakly Open-Vocabulary Semantic Segmentation

NeurIPS 2023poster

This paper studies the problem of weakly open-vocabulary semantic segmentation (WOVSS), which learns to segment objects of arbitrary classes using mere image-text pairs. Existing works turn to enhance the vanilla vision transformer by introducing explicit grouping recognition, i.e., employing severa…
