Abstract
An optimized dequantization array is proposed for the Joint
Photographers Expert Group (JPEG) scheme. The reconstruction error
is minimized subjected to a regularity constraint. Both the peak-topeak
signal-to-noise ratio (PPSNR) and the visual quality are improved.
In addition, the method reduces discontinuities in postprocessing such
as edge detection. This approach is in full compliance with the JPEG
standard.
