- W4293464694 abstract "Much research has been carried out into the automatic restoration of archival images. This research ranges from colourisation, to damage restoration, and super-resolution. Conversely, video restoration hasremained largely unexplored. Most efforts to date have involved extending a concept from image restoration to video, in a frame-by-frame manner. These methods result in poor temporal consistency between frames. This manifests itself as temporal instability or flicker. The purpose of this work is to improve upon this limitation. This improvement will be achieved by employing a hybrid approach of deep-learning and exemplar based colourisation. Thus, informing current frame colourisation about its neighbouring frame’s colourisations and therefore alleviating the inter-frame discrepancy issues. This paper has two main contributions. Firstly, a novel end-to-end automatic video colourisation technique with enhanced flicker reduction capabilities is proposed. Secondly, six automatic exemplar acquisition algorithms are compared. The combination of these algorithms and techniques allow for an 8.5% increase in non-referenced image quality over the previous state of the art." @default.
