In the image enlargement method, there are two techniques which are interpolation of pixel and presumption of high-frequency content.
In the first case, there is a problem that blurring is generated in the enlargement image.
In the second case, there is a problem that new artifact as ringing is added in the enlargement image.
In this paper, we extrapolate High-Frequency content by Discrete Wavelet transform.
The proposed method has possibility for reduction of noise that is generated by presumption failure, and represented effectiveness by the experimental result. |
