An Animation-based Augmentation Approach for Action Recognition from Discontinuous Video

no code implementations10 Apr 2024 Xingyu Song, Zhan Li, Shi Chen, Xin-Qiang Cai, Kazuyuki Demachi

(3) We achieve the same performance with only 10% of the original data for training as with all of the original data from the real-world dataset, and a better performance on In-the-wild videos, by employing our data augmentation techniques.
