Outline of Final Research Achievements

The objective of this research is the development of multi-channel video coding based on graph signal processing and colorization-based coding.
There are several research results such as the effective image colorization algorithm, the image coding technique using colorization, fast algorithms of the proposed algorithms, expanding to the video coding algorithm and depth image coding algorithm.
In particular, based on the graph-modeling of a color image, the algorithms of the colorization and the image coding have achieved a high performance.

Academic Significance and Societal Importance of the Research Achievements

近年、画像や動画の利用は様々な分野で増大しており、これに伴い高精度な画像処理手法や画像圧縮手法が求められるようになっている。また、従来のRGB画像だけでなく、深度画像や赤外線画像など、画像の種類も多様化している。
このような背景のもと、本研究ではチャネル間の相関関係を従来行われていたよりもより効率的に利用することによる、次世代動画像圧縮技術の開発を行い、高い性能を実現することに成功した。
