MODELISATION HYBRIDES POUR LA COMPRESSION D’IMAGES Application à la couche mince amorphe du matériau (V2O5-TeO2)

Abstract

The purpose of this work is to obtain compression ratio as high as possible using a hybrid method. The treatment is made line by line of the matrix image of the material (V2O5-TeO2) amorphous thin film by a model autoregressive and Gaussien , then we apply a discreet wavelet to improve the compression ratio. In the second party we apply the algorithm of Kohenen (self -organizing –feature-map) to have a high rate. In both cases we have to compare the compression ratio obtained with that of the JPEG.
