Query: SeqHAND:RGB-Sequence-Based 3D Hand Pose and Shape Estimation   3D hand pose estimation based on RGB images has been studied for a long time.
Most of the studies, however, have performed frame-by-frame estimation based on
independent static images. In this paper, we attempt to not only consider the
appearance of a hand but incorporate the temporal movement information of a
hand in motion into the learning framework for better 3D hand pose estimation
performance, which leads to the necessity of a large scale dataset with
sequential RGB hand images. We propose a novel method that generates a
synthetic dataset that mimics natural human hand movements by re-engineering
annotations of an extant static hand pose dataset into pose-flows. With the
generated dataset, we train a newly proposed recurrent framework, exploiting
visuo-temporal features from sequential images of synthetic hands in motion and
emphasizing temporal smoothness of estimations with a temporal consistency
constraint. Our novel training strategy of detaching the recurrent layer of the
framework during domain finetuning from synthetic to real allows preservation
of the visuo-temporal features learned from sequential synthetic hand images.
Hand poses that are sequentially estimated consequently produce natural and
smooth hand movements which lead to more robust estimations. We show that
utilizing temporal information for 3D hand pose estimation significantly
enhances general pose estimations by outperforming state-of-the-art methods in
experiments on hand pose estimation benchmarks.
