Simultaneous multi-frame MAP super-resolution video enhancement using spatio-temporal priors
Sean Borman, R.L. Stevenson · 2003
A simultaneous multi-frame super-resolution video reconstruction procedure, utilizing spatio-temporal smoothness constraints and motion estimator confidence parameters is proposed. The ill-posed inverse problem of reconstructing super-resolved imagery from the low resolution, degraded observations is formulated as a statistical inference problem and a Bayesian, maximum a-posteriori (MAP) approach is utilized for its approximate solution. The inclusion of motion estimator confidence parameters and temporal constraints result in higher quality super-resolution reconstructions with improved robustness to motion estimation errors.
