GA Optimisation of Spatio-Temporal Grey-Scale Soft Morphological Filters with Applications in Archive Film Restoration

A technique is described for the optimisation of spatio-temporal (3-D) grey-scale soft morphological filters for applications in archive film restoration. The optimisation is undertaken using genetic algorithms. By employing filters which incorporate the temporal dimension, this technique extends and improves upon previously described techniques which were based purely in the spatial (2-D) domain. Examples of applying the technique to real-world film restoration problems are shown.
