This paper proposes a method based on the Dempster-Shafer evidence theory for the detection of blotches in digitized archive film sequences. The detection scheme relies on the fusion of two uncorrelated fast, no motion compensated, spatio-temporal blotch detectors. The imprecision and uncertainty of botch detectors are modeled using Dempster-Shafer evidence theory, which improves the decision, by taking into acoount the ignorance and the conflict between detectors. We found that this combination scheme improves the global performance, and compares favorably to the motion compensated, complex and time consuming blotch detection methods, for reat archive film sequences.
