Abstract
Some image enlarging methods use extrapolation of high-frequency components. The image enlarging method using the Bezier surface has been proposed, where it is assumed that each pixel has energy. The pixel energy is invariant during the enlarging process. We propose a new method using the B-spline surface, and evaluate the effectiveness of the proposed method by using the PSNR value.
