Abstract : The problem of image interpolation using linear techniques is deal with in this paper. Conventional methods are changed into space-variant ones, by introducing the concept of both the biasing of signal value and the warping of distance among pixels. The biasing creates the peak of uneven signals which is corrspond to the signal details. The warping realizes the edge-preserving interpolation. This paper presents the method which is combined two concepts. The clear interpolated images can be obtained by the proposed method.
