What is an XGTF file?

XGTF files mostly belong to Viper. An XGTF (eXtensible Ground Truth Format) file is a specialized file format primarily used for storing video ground truth data. It is typically encoded using XML and is designed to facilitate the training and evaluation of computer vision algorithms, particularly those focused on video analysis. XGTF files contain structured annotations that describe various aspects of a video, such as object locations, actions, events, and other relevant information. This structured data serves as a reference or 'ground truth' against which the performance of video analysis algorithms can be measured.
