Abstract
In many restoration problems, the a-priori
knowledge of a finite number of pixel amplitudes of
the original image is available (e.g. blurred black-
and-white images). It is shown how to incorporate
this information into optimal image reconstruction.
The degradation of a discrete image is modeled as a
two-dimensional, finite-state Markov process. Dy-
namic programming is then applied to get an op-
timal estimate of the state sequence of that process
observed in memoryless noise, a technique which is
known as Viterbi algorithm. This leads to a nonli-
