Cata7 Dataset

Cata7 is the first cataract surgical instrument dataset for semantic segmentation. The dataset consists of seven videos while each video records a complete cataract surgery. All videos are from Beijing Tongren Hospital. Each video is split into a sequence of images, where resolution is 1920×1080 pixels. To reduce redundancy, the videos are downsampled from 30 fps to 1 fps. Also, images without surgical instruments are manually removed. Each image is labeled with precise edges and types of surgical instruments. This dataset contains 2,500 images, which are divided into training and test sets. The training set consists of five video sequences and test set consists of two video sequence.

Cata7乃语义分割领域首个白内障手术器械数据集。该数据集由七部视频组成，每部视频记录了一场完整的白内障手术过程。所有视频均采集自北京同仁医院。每部视频被分割为一系列图像，图像分辨率为1920×1080像素。为降低冗余，视频帧率由30帧/秒降至1帧/秒。此外，未包含手术器械的图像已人工剔除。每一图像均被标注了精确的边缘以及手术器械的类型。本数据集包含2,500张图像，分为训练集和测试集，其中训练集由五个视频序列组成，测试集则包含两个视频序列。
