A digital image interpolation method is disclosed which a projection point (x, y) of the original image corresponding to a pixel of the transformed image first is determined. According to neighboring pixels (m, n) of the projection point, Gauss weights Wi then are determined. Lastly, according to the...http://www.google.ca/patents/US7257276?utm_source=gb-gplus-sharePatent US7257276 - Digital image interpolation method
