[Mp4-tech] WMP vs JPEG-2000

[Dmitriy Vatolin]

Dear all!
   In May 2006 Microsoft presented a new format for images - WMP - as
   a replacement for JPEG 2000:
> The software maker detailed the new image format Wednesday at the
> Windows Hardware Engineering Conference here. Windows Media Photo will
> be supported in Windows Vista and also be made available for Windows
> XP, Bill Crow, program manager for Windows Media Photo, said in a
> presentation.
>
> In his presentation, Crow showed an image with 24:1 compression that
> visibly contained more detail in the Windows Media Photo format than
> the JPEG and JPEG 2000 formats compressed at the same level.
>
> Still, the image in the Microsoft format was somewhat distorted
> because of the high compression level. Typically digital cameras today
> use 6:1 compression, Crow said. Windows Media Photo should offer
> better pictures at double that level, he said. "We can do it in half
> the size of a JPEG file."

   We tested Microsoft's codec of this new format to compare it with 9
   JPEG 2000 image coders using PSNR and SSIM metrics.

   Hope they will be interesting for MPEG-4 guys.
