In the context of still image compression, some new représentation implemented with oriented lifting schemes has been conceived. For this thesis, three implementations of these transforms have been benchmarked upon a criteria considering the minimization of the high frequencies along the local direction of regularity. This orientation is estimated via edge extraction or minimization of a cost function. Both approaches lead to the classification of the directional activity of the image blocks. Those representations of the geometrical features that drive the oriented filtering process are coded in order to be transmitted to the decoder. The coding cost of these representations is compared. Finally an adaptive quantization is proposed to take in...
