We present an interpolation algorithm for digital images based on the extended Edge-Directed Interpolation. The proposed algorithm utilises localisation and orientation of edges extracted with wavelet edge extractors. The algorithm chooses an interpolation method of a given point of an image, depending on localisation with respect to extracted edges. We apply our method to grey scale digital images. In this paper we propose also some modifications to the method. We present the results obtained with our algorithm, in comparison to a few popular interpolation algorithms and we propose a plan of further algorithm extensions.
