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

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.
