Abstract
A simple exhaustive search technique is explored as a means
to design low-complexity reversible integer-to-integerwavelet
transforms for image coding applications. Several new trans-
forms found with this approach are employed in an image
coder in order to demonstrate their effectiveness.
1. Introduction
There has been a growing interest in reversible integer-
to-integer wavelet transforms for image coding applications
[17]. Such transforms are invertible in finite-precision arith-
metic (i.e., reversible), map integers to integers, and approx-
imate the linear wavelet transforms from which they are de-
rived. In this paper, we employ a simple exhaustive search
