Abstract :
A new image enlargement method for the estimation of high frequency image components lost in the sampling process is proposed. The method uses a codebook consisting of the low- and high-frequency components of an original image itself that is to be enlarged. The effectiveness of the proposed method is verified by comparing with conventional methods
