Query: TransRAC: Encoding Multi-scale Temporal Correlation with Transformers
  for Repetitive Action Counting   Counting repetitive actions are widely seen in human activities such as
physical exercise. Existing methods focus on performing repetitive action
counting in short videos, which is tough for dealing with longer videos in more
realistic scenarios. In the data-driven era, the degradation of such
generalization capability is mainly attributed to the lack of long video
datasets. To complement this margin, we introduce a new large-scale repetitive
action counting dataset covering a wide variety of video lengths, along with
more realistic situations where action interruption or action inconsistencies
occur in the video. Besides, we also provide a fine-grained annotation of the
action cycles instead of just counting annotation along with a numerical value.
Such a dataset contains 1,451 videos with about 20,000 annotations, which is
more challenging. For repetitive action counting towards more realistic
scenarios, we further propose encoding multi-scale temporal correlation with
transformers that can take into account both performance and efficiency.
Furthermore, with the help of fine-grained annotation of action cycles, we
propose a density map regression-based method to predict the action period,
which yields better performance with sufficient interpretability. Our proposed
method outperforms state-of-the-art methods on all datasets and also achieves
better performance on the unseen dataset without fine-tuning. The dataset and
code are available.
