Long-Term Human Video Generation of Multiple Futures Using Poses
Predicting future human behavior from an input human video is a useful task
for applications such as autonomous driving and robotics. While most previous
works predict a single future, multiple futures with different behavior can
potentially occur. Moreover, if the predicted future is too short (e.g., less
than one second), it may not be fully usable by a human or other systems. In
this paper, we propose a novel method for future human pose prediction capable
of predicting multiple long-term futures. This makes the predictions more
suitable for real applications. Also, from the input video and the predicted
human behavior, we generate future videos. First, from an input human video, we
generate sequences of future human poses (i.e., the image coordinates of their
body-joints) via adversarial learning. Adversarial learning suffers from mode
collapse, which makes it difficult to generate a variety of multiple poses. We
solve this problem by utilizing two additional inputs to the generator to make
the outputs diverse, namely, a latent code (to reflect various behaviors) and
an attraction point (to reflect various trajectories). In addition, we generate
long-term future human poses using a novel approach based on unidimensional
convolutional neural networks. Last, we generate an output video based on the
generated poses for visualization. We evaluate the generated future poses and
videos using three criteria (i.e., realism, diversity and accuracy), and show
that our proposed method outperforms other state-of-the-art works
