Key frames-based video super-resolution using adaptive overlapped block motion compensation

Abstract

A video super resolution algorithm is presented, which is based key frame and adaptive overlapped block motion compensation(AOBMC). First, the key frames are high resolution frames and are seen as references; non-key frames are low resolution frames and are up-sampled the same size as the key frames. Then, non-key frames are super resolved by adaptive overlapped block motion compensation using adjacent high resolution key frames. The experimental results indicate the improved performance of proposed super-resolution algorithm on both the subjective visual quality and PSNR.
