Query: Manipulation-skill Assessment from Videos with Spatial Attention Network   Recent advances in computer vision have made it possible to automatically
assess from videos the manipulation skills of humans in performing a task,
which breeds many important applications in domains such as health
rehabilitation and manufacturing. Previous methods of video-based skill
assessment did not consider the attention mechanism humans use in assessing
videos, limiting their performance as only a small part of video regions is
informative for skill assessment. Our motivation here is to estimate attention
in videos that helps to focus on critically important video regions for better
skill assessment. In particular, we propose a novel RNN-based spatial attention
model that considers accumulated attention state from previous frames as well
as high-level knowledge about the progress of an undergoing task. We evaluate
our approach on a newly collected dataset of infant grasping task and four
existing datasets of hand manipulation tasks. Experiment results demonstrate
that state-of-the-art performance can be achieved by considering attention in
automatic skill assessment.
