SurgicalPart-SAM: Part-to-Whole Collaborative Prompting for Surgical Instrument Segmentation

2 code implementations22 Dec 2023 Wenxi Yue, Jing Zhang, Kun Hu, Qiuxia Wu, ZongYuan Ge, Yong Xia, Jiebo Luo, Zhiyong Wang

Specifically, we achieve this by proposing (1) Collaborative Prompts that describe instrument structures via collaborating category-level and part-level texts; (2) Cross-Modal Prompt Encoder that encodes text prompts jointly with visual embeddings into discriminative part-level representations; and (3) Part-to-Whole Adaptive Fusion and Hierarchical Decoding that adaptively fuse the part-level representations into a whole for accurate instrument segmentation in surgical scenarios.
