  This paper presents an approach to forecast future presence and location of
human hands and objects. Given an image frame, the goal is to predict what
objects will appear in the future frame (e.g., 5 seconds later) and where they
will be located at, even when they are not visible in the current frame. The
key idea is that (1) an intermediate representation of a convolutional object
recognition model abstracts scene information in its frame and that (2) we can
predict (i.e., regress) such representations corresponding to the future frames
based on that of the current frame. We design a new two-stream convolutional
neural network (CNN) architecture for videos by extending the state-of-the-art
convolutional object detection network, and present a new fully convolutional
regression network for predicting future scene representations. Our experiments
confirm that combining the regressed future representation with our detection
network allows reliable estimation of future hands and objects in videos. We
obtain much higher accuracy compared to the state-of-the-art future object
presence forecast method on a public dataset.
