Multidirectional parabolic prediction-based interpolation-free sub-pixel motion estimation
作者:
Highlights:
• Multidirectional parabolic prediction patterns are developed to reduce coding loss.
• Projection is introduced to improve each directional parabolic prediction pattern.
• A prediction enhancement mechanism is presented by incorporating AMVP information.
• Significant complexity reduction (about 90%) of sub-pixel ME is achieved over HM16.0.
• Proposed algorithm outperforms state-of-the-art algorithms with improved coding performance.
