A test for isotropy of images modeled as stationary
or intrinsically stationary random fields on a lattice is developed.
The test is based on wavelet theory, and can operate on the
horizontal and vertical scale of choice, or on any combination
of scales. Scale is introduced through the wavelet variances
(sometimes referred to as the wavelet power spectrum), which
decompose the variance over ...
