Local motion-adaptive interpolation technique based on block matching algorithms

摘要

Interpolation techniques based on block-by-block motion compensation algorithms are studied for the video conference/video telephone signals. In this paper, we propose the local motion-adaptive interpolation technique, which can be used in the codec using a motion compensated coding-block matching algorithm (MCC-BMA). Computer simulation results at 2:1 subsampling rate of the proposed local motion-adaptive interpolation techniques combined with the conventional three-step search algorithm and the fast BMA using integral projections are given.
