Teacher Tracking Dataset

There are two types of sequences: real-lecture videos and challenges videos. The real-lecture category consists of two long duration videos (30 minutes each) that have been recorded in a real lecture; they present some difficulties as target disappearing and reappearing on the scene, target appearance changes and scene illumination changes.

In addition to the two long videos, 10 short different challenges videos designed to include difficult situations that a tracking algorithm might face during a lecture have been recorded with the aim of testing the algorithm in these situations. C1 presents the target taking off a sweater, which represents a high appearance change. In C2 and C3, the tracked target leaves the scene and then comes back to it. In C2, the exit and entry are produced in the same place, different than C3 in which they are produced at different locations. A significant occlusion is shown in C4, where the target moves and hides behind the blackboard coming out on the opposite end of it. In C5, the target squats (for example, to turn on a computer) behind a table. The challenge presented in C6 is similar than the one presented in C4, but in this case the target comes in on the same place where he came out. Both C7 and C8 present people and target crossing situations with people wearing similar (dark) clothes. C9 shows a situation where the target sits down and waits while two people with similar appearance go on stage sequentially. Finally C10 shows a target spinning.
