Abstract:- In this paper, we propose an image reconstruction method utilizing an optimized adaptive interpolation kernel along with a 2D M-channel perfect reconstruction filter bank(M-ch PR-FB) structure. In particular, the proposed approach leads to sharper reconstructed images than a direct conversion, still preserving high frequency components of the original image by employing the subband processing of a 2D M-ch PR-FB. Finally, the image quality improved by the proposed approach is demonstrated by comparing with those of the direct conversion methods using the bicubic and adaptive 2 nd Newton interpolation kernels.
