AI总结:

本研究提出SurgeNetXL,通过大规模预训练提升手术计算机视觉性能,实现多个任务上的显著改进。

摘要:

基础模型通过在大规模数据集上进行大规模预训练,在计算机视觉领域实现了在多种任务上的大幅超群性能。然而,其在手术计算机视觉中的应用受到限制。本研究通过引入SurgeNetXL,一种新的手术基础模型,填补了这一空白。该模型在迄今为止最大的手术数据集上进行训练,包含超过470万帧视频。SurgeNetXL在六个跨越四种手术程序和三种任务的数据集上均实现了稳定的一线性能,包括语义分割、阶段识别和关键视图安全性(CVS)分类。与表现最佳的手术基础模型相比,SurgeNetXL在语义分割、阶段识别和CVS分类任务上分别显示出2.4、9.0和12.6个百分点的平均改进。此外,SurgeNetXL在相应任务上比最佳的ImageNet变体分别高出14.4、4.0和1.6个百分点。除了提高模型性能外,本研究还提供了关于扩展预训练数据集、延长训练时间以及优化模型架构以适应手术计算机视觉的关键见解。这些发现为在数据稀缺场景中提高通用性和鲁棒性铺平了道路,为该领域未来研究提供了全面的框架。所有模型和SurgeNetXL数据集的一个子集,包括超过200万帧视频,均在https://github.com/TimJaspers0801/SurgeNet上公开。

英文摘要:

Foundation models have revolutionized computer vision by achieving vastly superior performance across diverse tasks through large-scale pretraining on extensive datasets. However, their application in surgical computer vision has been limited. This study addresses this gap by introducing SurgeNetXL, a novel surgical foundation model that sets a new benchmark in surgical computer vision. Trained on the largest reported surgical dataset to date, comprising over 4.7 million video frames, SurgeNetXL achieves consistent top-tier performance across six datasets spanning four surgical procedures and three tasks, including semantic segmentation, phase recognition, and critical view of safety (CVS) classification. Compared with the best-performing surgical foundation models, SurgeNetXL shows mean improvements of 2.4, 9.0, and 12.6 percent for semantic segmentation, phase recognition, and CVS classification, respectively. Additionally, SurgeNetXL outperforms the best-performing ImageNet-based variants by 14.4, 4.0, and 1.6 percent in the respective tasks. In addition to advancing model performance, this study provides key insights into scaling pretraining datasets, extending training durations, and optimizing model architectures specifically for surgical computer vision. These findings pave the way for improved generalizability and robustness in data-scarce scenarios, offering a comprehensive framework for future research in this domain. All models and a subset of the SurgeNetXL dataset, including over 2 million video frames, are publicly available at: https://github.com/TimJaspers0801/SurgeNet.
