Title: Detecting Actions in Videos Using Less Labelled Data
Abstract: Video action detection is an active area of research with applications to performance assessment and monitoring, anomaly and hazard detection, and human-robot interaction, among others. Existing approaches rely on large, labelled datasets which are costly to collect and annotate at scale. This makes them unsuitable for applications where only a small amount of data is available overall, multiple examples of certain action classes are not available, or it is infeasible to manually annotate the amount of data required.
We present ongoing work towards developing methods capable of recognising and segmenting actions in continuous video streams using substantially less labelled data than existing methods. Our work proposes a novel method that combines concepts in few-shot learning and unsupervised segmentation of time-series data, with preliminary test results discussed.
