		<abstract>Digital image interpolation techniques are frequently used to  enlarge pictures, i.e. zooming in, and they are upon increasingly  demand for developing product applications using digital still  cameras. One common difficulty with conventional interpolation  techniques is that of preserving details, i.e. edges, and at the same time smoothing the data for not introducing spurious artifacts.  A definitive solution to this is still an open issue, although  there are working methods in the market, see e.g. Parker et.  al. [6], Sakamoto et. al. [8] for recent surveys. In this paper  we propose a locally adaptive edge-preserving algorithm for  image interpolation, which deals with this problem, and different  than other methods shows how to compute local thresholds preserving edges and not destroying smoothness at the same time.</abstract>
