- Abstract
- In this paper, we propose the method for magnification of a single image by modifying DCT coefficients. The proposed method modifies DCT coefficients using a reference map that indicates variations of pixel values according to the image magnification. Experimental results show that the performance of our method has been improved by 7% over the conventional methods. © 2012 IEEE.
