Abstract
Image enlargement method using linear interpolation causes blur because edge is extend as same as non-edge region. In this paper, we have proposed image enlargement method for preservation of edge using quadratic Bezier curve. Our method calculates fitting curves each scan lines in the image and makes enlargement image by extending fitting curves with preservation of edge. As a result, it is seen that the proposal method doesn't have blur in the enlargement image compared with linear interpolation method.
