This thesis is concerned with multiresolution decompositions in a lifting scheme framework as well as its application to image compression. First, a decomposition structure consisting of a "generalized lifting scheme" is proposed, using all information available in the decoding stage for prediction. This new scheme relies on an additional predictive filter which does not appear in classical lifting scheme structures. The proposed scheme is then associated to two adaptation methods. The first one, called GAE, assumes a global stationnarity of the image, while the second one, called LAE assumes only a local stationnarity. In the latter, adaptive filters are used. A study of the performance in lossless coding is done by using a set of Gaussien...
