Advances in the detection and reconstruction of blotches in archived film and video
Anil C. Kokaram · 2001
There have been several proposals for the detection and reconstruction of missing data as it applies to the restoration of archived film and video. The essence of many of the schemes is that missing data can be characterised as impulsive distortion along motion trajectories in an image sequence. This observation, coupled with a model of an image sequence leads to the design of both detection and correction schemes. This paper presents a single probabilistic framework which unifies the principal issues in blotch treatment. A number of schemes are examined within this framework and results are shown comparing the performance of a complete application of the framework with previous schemes. The idea is to show how a variety of different approaches are unified within one probabilistic framework, and that the implementation of the framework can be made practical. (6 pages)
