In this paper, in order to realize the image enlargement with high performance, we propose a new enlargement method, which restores high-frequency components lost in the interpolation-based methods, by using high-frequency estimation. The estimation is based on the eigenspace method proposed by Amano et al.. The proposed enlargement method can generate lost high-frequency components by using pairs...
A high-quality image enlargement is achieved by an estimation of high-frequency component. A codebook based method, which consists of a relationship of high and low-frequency image components, is known as one of the high-quality image enlargement. However, it takes too much calculation time, and is not appropriate for a real-time application such as a moving image enlargement. In this paper, we propose...
