The intent of this paper is to optimize the subband coding
scheme by exploiting the psychovisual properties of the human
visual system, such that high perceptual quality of the
compressed image can be maintained at very low bit rates. In
order to reach the optimality where the coding impairment is
invisible or minimally noticeable at a given viewing distance,
the approach of JND/MND profile is conducted in two aspects.
One is to develop an effective HVS model for obtaining an
accurate JNDMND profile by which the perceptual redundancy
is quantified. The other is to design a subband coding
