Unsupervised & Semi-Supervised Domain Adaptation for Action Recognition From Drones
WACV 2020 | We address the problem of human action classification in drone videos. Due to the high cost of capturing and labeling large-scale drone videos with diverse actions, we present unsupervised and semi-supervised domain adaptation approaches that leverage both the existing, fully-annotated action-recognition datasets and unannotated (or only a few annotated) videos from drones. To study the emerging problem of drone-based action recognition, we create a new dataset, NEC-DRONE, containing 5,250 videos to evaluate the task. We tackle both problem settings with same and different action label sets for the source (e.g. Kinetics dataset) and target domains (drone videos).
