  • Publication number: 20240020887
    Abstract: An Online Meta Learning (“OML”) framework is provided for learned image compression (“LIC”) based on a variable-rate Conditional Variational Auto-Encoder (“CVAE”) architecture. A computing system is configured to learn, from multiple training tasks of compression with different RD tradeoff ?s, a set of task-general meta parameters controlled by meta-control variables ?. Meta parameters learn a mapping between the meta-control variables ? and compression effects of different RD tradeoffs ?s. Meta-control variables ? are adaptively determined and transmitted on the fly to an encoder and a decoder of an image compression process, to accommodate the current compression need for any current test datum. A parallelized context computation method is also provided for an online CVAE-based meta-LIC architecture; since OML requires multiple iterations at an encoder, parallel context estimation substantially improves computational time in practice.
