Countix

Countix 是在野外收集的重复视频的真实世界数据集（即 YouTube），涵盖了广泛的语义设置，具有重大挑战，例如相机和对象运动、不同的周期和计数集以及重复动作的速度变化。 Countix 包括重复的锻炼活动视频（深蹲、引体向上、战绳训练、锻炼手臂）、舞蹈动作（旋转、抽拳）、演奏乐器（弹尤克里里）、反复使用工具（锤击物体、电锯切割木头、切片洋葱）、艺术表演（呼啦圈、杂耍足球）、运动（打乒乓球和网球）等等。图 6 说明了数据集中的一些示例以及重复计数和周期长度的分布。

Countix is a real-world dataset of repetitive videos collected from the wild (i.e., YouTube), covering a wide range of semantic scenarios with significant challenges including camera and object motions, diverse cycles and count sets, and varying speeds of repetitive actions. Countix includes repetitive exercise activity videos (squats, pull-ups, battle rope training, arm exercises), dance movements (rotations, punching), musical instrument playing (ukulele playing), repeated tool use (hammering objects, chainsaw cutting wood, slicing onions), artistic performances (hula hooping, juggling footballs), sports (playing table tennis and tennis), and more. Figure 6 illustrates some examples from the dataset as well as the distribution of repetitive counts and cycle lengths.
