dc.description.abstract | Automated blotch removal is important in film restoration and
typically involves a detection/interpolation step. Current algorithms
model the corruption as a binary mixture between
the original, clean images and an opaque (dirt) field. This
typically causes incomplete blotch removal that manifests as
blotch haloes in reconstruction. This paper proposes a new
approach by modeling the corruption as a continuous mixture
between the two components and generating a solution using
a Bayesian framework. We use novel priors, propose a
computationally efficient scheme for implementation and our
results show more complete blotch reconstruction. | en |
