The Future
of JPEG The current JPEG standard provides excellent performance at rates above 0.25
bits per pixel. However, at lower rates there is a sharp degradation in the quality of the
reconstructed image. To correct this and other shortcomings, the JPEG committee initiated
work on another standard, commonly known as JPEG 2000. To date, only a few aspects of JPEG
2000 are certain, including the intention to base the standard on wavelet decomposition.
The remainder of the JPEG 2000 standard is in the process of being reviewed. |
