DnS: Distill-and-Select for Efficient and Accurate Video Indexing and Retrieval. (arXiv:2106.13266v3 [cs.CV] UPDATED)

In this paper, we address the problem of high performance and computationally
efficient content-based video retrieval in large-scale datasets. Current
methods typically propose either: (i) fine-grained approaches employing
spatio-temporal representations and similarity calculations, achieving high
performance at a high computational cost or (ii) coarse-grained approaches
representing/indexing videos as global vectors, where the spatio-temporal
structure is lost, providing low performance but also having low computational
cost. In this work, we propose a Knowledge Distillation framework, called
Distill-and-Select (DnS), that starting from …
