Abstract

In this paper, reversible subband coding of images are proposed. The high-band signals of conventional one-dimensional reversible filter banks were extrapolative prediction error signals or interpolative ones of which number of levels became four times that of the input signals. Therefore, we design reversible filter banks that generate interpolative prediction error signals of which number of levels becomes twice that of the input signals. We also design nonseparable filter banks. It is shown that the proposed methods have the better performance than the conventional reversible subband coding and that the separable method with low-pass filter has little aliasing in the reduced images.
