Personalized OV Semantic Segmentation

Updated 6 July 2026
  • Personalized OVSS is a method that uses a few support image–mask pairs to define a user-specific visual concept within the open-vocabulary framework.
  • It integrates a personalized text token with standard CLIP embeddings through prompt tuning, negative mask proposals, and visual embedding injection to enhance segmentation precision.
  • Empirical evaluations show significant improvements in personal IoU with minimal impact on overall mIoU, demonstrating a flexible plug-in solution for user-specific segmentation tasks.
