TRECVID is the premier annual international workshop event for evaluating content-based retrieval of multimedia and digital video. The workshop organizes a set of different tracks by providing data, task definition, metrics, and evaluation protocols to participants. During the workshop, participants submit notebook papers, discuss results, and benefit from sharing their experiences about which methods work and what does not work and why?!
With its high quality and low cost, it provides an exceptional value for students, academics and industry researchers.
