Comparative Study of Near-Lossless Compression by JPEG XR, JPEG 2000, and H.264 on 4K Video Sequences - Advances in Image and Graphics Technologies - page 37

• JPEG 2000

Official software Jasper is used. Parameters are set as:

─ Tile size: 3840x2160
─ Code-block size: 64
─ DWT Level: 4
─ Rate 0.03, 0.05, 0.07, 0.1, 0.15

• H.264

4 profiles are chosen, including AVC inter, IPP, IP and Intra. Parameters are set as
the following table.

Experimental Results
The rate-distortion result in terms of average PSNR of 5 video sequences is shown in
Fig 10. 7 encoding methods is compared in Table 4, including AVC inter, AVC intra,
AVC IPP, AVC IP, JPEG 2000, JPEG XR.OF0 and JPEG XR OF1.
