Symmetric-extension-compatible reversible integer-to-integer wavelet transforms

Two Families of Symmetry-preserving Reversible Integer-to-integer Wavelet Transforms

Two families of symmetry-preserving reversible integer-to-integer wavelet transforms are introduced. Briefly, we explain how transforms from these families can be used in conjunction with symmetric extension in order to handle signals of arbitrary length in a nonexpansive manner (which is often a desirable attribute in signal coding applications). The characteristics of the two transform famili...

Low-Complexity Reversible Integer-to-Integer Wavelet Transforms for Image Coding

Abstract A simple exhaustive search technique is explored as a means to design low-complexity reversible integer-to-integer wavelet transforms for image coding applications. Several new transforms found with this approach are employed in an image coder in order to demonstrate their effectiveness.

Reversible integer-to-integer wavelet transforms for image compression: performance evaluation and analysis

In the context of image coding, a number of reversible integer-to-integer wavelet transforms are compared on the basis of their lossy compression performance, lossless compression performance, and computational complexity. Of the transforms considered, several were found to perform particularly well, with the best choice for a given application depending on the relative importance of the preced...
