Develop and evaluate a class of video super-resolution algorithms under the maximum a posteriori framework utilizing a novel multichannel image prior.
Formulated a maximum a posteriori (MAP) estimation framework integrating single-channel observation models with a novel multichannel image prior.
Designed a hierarchical, two-level Gaussian nonstationary extension of the multichannel prior to model complex spatio-temporal variations.
Evaluated algorithm performance through comparative numerical experiments against existing single-channel and benchmark super-resolution techniques.
Multichannel image prior algorithms achieved superior high-resolution reconstruction quality compared to conventional single-channel baselines.
The hierarchical Gaussian nonstationary formulation demonstrated consistent qualitative and quantitative performance advantages across comparative numerical benchmarks.
