Query: Non-uniform Quantization of Detail Components in Wavelet Transformed
  Image for Lossy JPEG2000 Compression   The paper introduces the idea of non-uniform quantization in the detail
components of wavelet transformed image. It argues that most of the
coefficients of horizontal, vertical and diagonal components lie near to zeros
and the coefficients representing large differences are few at the extreme ends
of histogram. Therefore, this paper advocates need for variable step size
quantization scheme which preserves the edge information at the edge of
histogram and removes redundancy with the minimal number of quantized values.
To support the idea, preliminary results are provided using a non-uniform
quantization algorithm. We believe that successful implementation of
non-uniform quantization in detail components in JPEG-2000 still image standard
will improve image quality and compression efficiency with lesser number of
quantized values.
