该数据集包含了在八次根治性前列腺切除手术中收集的内镜视频，这些视频针对四个评估手术流程的任务进行了标注。数据集特别指出了类别分布的不均衡性，其中一些出现频率较低的类别对应于偶发的手术事件。该数据集规模涵盖了73,618个关键帧，并标注了5,804个仪器实例，其任务包括阶段和步骤识别、仪器检测以及原子动作识别。This dataset comprises endoscopic videos collected from eight radical prostatectomy surgeries, with annotations for four surgical workflow evaluation tasks. The dataset explicitly notes the class imbalance issue, where some infrequently occurring categories correspond to incidental surgical events. It includes 73,618 key frames and 5,804 annotated instrument instances, and its associated tasks are phase and step recognition, instrument detection, and atomic action recognition.
