dc.description.abstractIn some applications of digital image processing the fact that an image is a non estacionary signal can cause some undesirable effects. That is the case of block effect in transform coding, or destructive effects on contours in interpolation or decimation images. This paper deals with interpolation image case carried out by a previous segmentation of the image in estacionary regions, which can be interpolated in a classical way. The results have been applicated for zooming purposes, and in multirresolution image decomposition in order to reduce the error in decimation-interpolation process.
