Abstract—We propose a technique for super-resolution imaging
of a scene from observations at different camera zooms. Given a sequence
of images with different zoom factors of a static scene, we
obtain a picture of the entire scene at a resolution corresponding to
the most zoomed observation. The high-resolution image is modeled
through appropriate parameterization, and the parameters
are learned from the most zoomed observation. Assuming a homogeneity
of the high-resolution field, the learned model is used
as a prior while super-resolving the scene. We suggest the use of
either a Markov random field (MRF) or an simultaneous autoregressive
(SAR) model to parameterize the field based on the computation
one can afford.We substantiate the suitability of the proposed
method through a large number of experimentations on both
simulated and real data.
