Identification and discussion of open issues in perceptual video coding based on image analysis and completion
Abstract
Perceptual video coding (VC) based on image analysis and completion (IAC) has enjoyed increasing awareness during the past few years. Many related approaches have been proposed that follow diverging strategies: from full compatibility to hybrid block transform coding to alternative codec design. Hence, in this paper, the most significant issues in IAC coding will be identified and their relevance for the IAC VC design highlighted. It will be analyzed where the most promising pathways lie and justified why others may be limited in their potentialities. Discussions will be substantiated using new methods developed by the authors for block-based and region-based IAC coding additionally to the state-of-the-art approaches.
