Abstract

Abstract : A bi‐directional deformable block‐based motion‐estimation algorithm to improve the accuracy of a motion prediction in a 360‐degree video, used for motion compensated frame‐rate up conversion (MC‐FRUC) is proposed. The block shapes are adaptively deformed to predict a motion based on the coordinate of the current block, considering the geometric property of the equi‐rectangular projection of 360‐degree videos. Experimental results demonstrate that the proposed technique can significantly improve the visual quality of the videos as compared with the conventional MC‐FRUC.
