OCSampler: Compressing Videos to One Clip with Single-step Sampling. (arXiv:2201.04388v1 [cs.CV])

In this paper, we propose a framework named OCSampler to explore a compact
yet effective video representation with one short clip for efficient video
recognition. Recent works prefer to formulate frame sampling as a sequential
decision task by selecting frames one by one according to their importance,
while we present a new paradigm of learning instance-specific video
condensation policies to select informative frames for representing the entire
video only in a single step. Our basic motivation is that the efficient …
