Abstract

In this paper, an idea for the combination of global andlocal view models is presented. These two type of modelshave proved their capabilities independantly. Some combinationwere proposed, using global view models for localanalysis, and local view models to synthetize local results.An opposite approach is proposed here : local view modelsare used as a normalization tool, while global view modelsare used for the recognition of the normalized image.The use of local view models for normalization is justifiedby their capability to perform a non-linear normalizationaccording to the image information. We propose Markovmodels as local view models, and Neural Netwok as globalview models. Using Markov models for the normalizationincreases results up to 3% better than a classical linearnormalization. Global results are improved, performing2% better than the Markov model itself. The extension ofthe system to an analytic approach is discussed.
