Outline of Final Research Achievements

To put into practical use new "similar inter-frame prediction" and "differential signal adaptive conversion" for high-performance video integrated coding corresponding to various high-performance video, such as free-point view video, free-focus view video, high dynamic range video, hyperspectral video, we proposed many transforms that can be a low-complexity and high-efficiency basic technology. On the other hand, we researched on the security of coding. As a result, we presented six journal articles and 23 conference presentations in and outside of Japan.
