Understanding Personal Concept in Open-Vocabulary Semantic Segmentation

While open-vocabulary semantic segmentation (OVSS) can segment an image into semantic regions based on arbitrarily given text descriptions even for classes unseen during training, it fails to understand personal texts (e.g. 'my mug cup') for segmenting regions of specific interest to users. This paper addresses challenges like recognizing 'my mug cup' among 'multiple mug cups'. To overcome this challenge, we introduce a novel task termed personalized open-vocabulary semantic segmentation and propose a text prompt tuning-based plug-in method designed to recognize personal visual concepts using a few pairs of images and masks, while maintaining the performance of the original OVSS. Based on the observation that reducing false predictions is essential when applying text prompt tuning
