Contrastive Masked Autoencoders for Self-Supervised Video Hashing. (arXiv:2211.11210v2 [cs.CV] UPDATED)

Self-Supervised Video Hashing (SSVH) models learn to generate short binary
representations for videos without ground-truth supervision, facilitating
large-scale video retrieval efficiency and attracting increasing research
attention. The success of SSVH lies in the understanding of video content and
the ability to capture the semantic relation among unlabeled videos. Typically,
state-of-the-art SSVH methods consider these two points in a two-stage training
pipeline, where they firstly train an auxiliary network by instance-wise
mask-and-predict tasks and secondly train a hashing model to preserve …
