Super-resolution
Basic idea:
define a destination (dst) image of desired resolution
assume mapping from dst to each input image is known
usually a combination of a 2D motion/warp and an average
(point-spread function)
can be expressed as a set of linear constraints
sometimes the mapping is solved for as well
add some form of regularization (e.g., “smoothness
assumption”)
can also be expressed using linear constraints
but L1, other nonlinear methods work better
