This paper proposes a new method to improve the performance of traditional interpolation -based image magnification methods. Starting from a pyramidal model for multiresolution representation of an image, we observe the relationship of images at different resolutions. From this model, a new technique for image magnification is proposed. The new method introduces the concept of a compensation image, which is used to compensate the components of the magnified image that are lost during the interpolation process. The original contributions of this work also include the use of vector quantization to generate the compensation image. We will provide experimental results to demonstrate the improvements achieved by the proposed techniqu
