Abstract:
Line scratches are a common form of degradation in
archived motion picture film. The automatic restoration
of such, material has become of increasing interest
in the last few years with the rase of consumer digital
video applications and the need to supply more programming
material of an acceptable quality in a multimedia
context. This paper introduces mechanisms for
removing line artefacts from degraded images. It also
proposes schemes which solve for both the image data
and the hidden model parameters simultaneously. The
algorithms introduced are based on the use of the 2DAR
process as an underlying image model and employ a
Bayesian approach. The Gibbs sampler is used to draw
samples from the underlying image texture and so create
a convincing interpolation in the region previously
obscured by the line feature.
