The quadtree-structured decomposition of images is used in image compression in order to have a low cost region description associated with a particular transform. When this transform is reduced to the mean value on each block, high compression ratios can be obtained. However, in this case a blocking effect arises. In the paper, a reconstruction method using smooth non-symmetrical interpolation functions is introduced. This method represents the information of the tree in a far more satisfactory way for the visual system than non-overlapping blocks reconstruction.<>
