VRP-SAM: SAM with Visual Reference Prompt

2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
In this paper, we propose a novel Visual Reference Prompt (VRP) encoder that empowers the Segment Anything Model (SAM) to utilize annotated reference images as prompts for segmentation, creating the VRP-SAM model. In essence, VRP-SAM can utilize annotated reference images to comprehend specific objects and perform segmentation of specific objects in ...
