A ToF 3D database for hand gesture recognition

Although 3D information presents, in the context of hand gesture recognition (and not only), multiple advantages in comparison with the 2D counterpart, up-to-date there are very few 3D hand gesture databases. Recently, the Time-of-Flight (ToF) principle - employed in certain range imaging 3D cameras - became more and more attractive. According to it, the measurement distance is derived from the propagation time of the light pulse between the camera and the subject for each point of the image. In this paper, we describe the development of UPT ToF 3D Hand Gesture Database (UPT-ToF3D-HGDB). It represents, according to the best of our knowledge, the single database of this type which is publicly available.
