Towards Effective Surgical Representation Learning with DINO Models
Proceedings of The 9th International Conference on Medical Imaging with Deep Learning, PMLR 315:1065-1080, 2026.
Abstract
Self-supervised learning (SSL) has emerged as a promising approach to address the limitations of annotated surgical datasets, which are often small, heterogeneous, and expensive to curate. Among SSL methods, self-distillation with no labels (DINO) has achieved state-of-the-art (SOTA) results in natural images, but its applicability to surgical data remains underexplored. In this work, we systematically investigate DINOv1, DINOv2, and DINOv3 for surgical representation learning. We pretrain these models on a large-scale surgical dataset of 4.7M video frames (SurgeNetXL) and evaluate their transferability on downstream tasks including semantic segmentation and surgical phase recognition. Our results demonstrate that in-domain pretraining consistently improves performance across all DINO variants, with DINOv2 and DINOv3 achieving SOTA performance. We further offer practical insights and visualizations highlighting the effectiveness of SSL. Finally, our study delivers ready-to-use DINO-based SSL models and pretraining protocols for surgical computer vision research, which are publicly available at: github.com/rlpddejong/SurgeNetDINO.
