| Abstract: | Super resolution image restoration can reconstruct spatial frequencies information above the limit frequency to get more details of image.Multi-frame super-resolution restoration is a technique for estimating an unaliased high resolution image from an aliased video sequence and combating additive noise and blurring due to the finite detector size and optics.It needs to know sub-pixel motion between image sequences.Micro-scan technology can be used to obtain sup-pixel motion between image sequences.An improved Bayesian MAP estimator regularization for super-resolution restoration is proposed. |
