This paper introduces a very low complexity visual masking algorithm for the
JPEG2000 image compression standard and evaluates its impact on the visual
image quality by means of the Multi-scale SSIM index. The algorithm derives
suitable weighting masks indirectly from a statistical model of the wavelet
data which is defined from the second moment and the average absolute amplitude of
the data. If combined with an a priori rate allocation algorithm, the
computation of the visual masking weights has almost no overhead at all.
