Dataset folder structure. LapGC-KVAD-30 has three subsets (training, validation, and test) and a file named “color.json”. The training, validation, and test sets contain 20, 5, and 5 folders respectively. Each folder corresponds to a single case and contains eight subfolders, which include frames, segmentation annotations, and a CSV file that stores the names of all files along with their corresponding information. The “color.json” file stores the RGB values of the colors for fifteen types of key vessels. For better understanding, we visualized the “color.json” file as a table and displayed the color corresponding to each RGB value. LapGC-KVAD-30: Laparoscopic Gastric Cancer Key Vascular Anatomy Dataset; SMU-NF-GC-01 Dataset: Southern Medical University-Nanfang Hospital-Gastric Cancer-01 Dataset; RGB: Red-Green-Blue.
