DR-P1 See [DR8] Performance comparison of HEVC, DIRAC and H.264/AVC using CIF and QCIF test sequences shows, in general, superior performance of HEVC.

Extend this comparison to SD, HDTV, UHDTV, 4K and 8K test sequences. See also [DR9].

DR.P2 Fracastoro, Fossen and Magli [E392] developed steerable DCT (SDCT) and its integer approximation and applied them to image coding. They also compared this with wavelet coding (Table III). Confirm the results shown in this Table and extend this to higher resolution images.

DR.P3 See [E393]. Apply the FCDR to DIRAC codec both as a post processing operation and as an in loop (embedded) operation. Implement the projects for DIRAC similar to those described in P.5.268 and P.5.269.


DAALA


DAALA1 T.J. Daede et al, “A perceptually-driven next generation video codec” , IEEE DCC, Snow Bird, Utah, March-April 2016. Abstract of this paper is repeated here:

The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like PSNR. This paper documents some of our experiences with these tools, which ones worked and which did not, and what we have learned from them. The result is a codec which compares favorably with HEVC on still images, and is on a path to do so for video as well.

Daala video compression

Daala is the code-name for a new video compression technology. The effort is a collaboration between Mozilla Foundation, Xiph.Org Foundation and other contributors.

The goal of the project is to provide a free to implement, use and distribute digital media format and reference implementation with technical performance superior to h.265.


Technology demos

  • Next generation video: Introducing Daala

  • Introducing Daala part 2: Frequency Domain Intra Prediction

  • Introducing Daala part 3: Time/Frequency Resolution Switching

  • Introducing Daala part 4: Chroma from Luma

  • Daala: Painting Images For Fun (and Profit?)

  • Daala: Perceptual Vector Quantization (PVQ)

Etikala final report. This report implemented both HEVC and DALLA and compares their performances in terms of R-D plots for CIF and QCIF test sequences.

DAALA4 J.-M. Valin et al, “DAALA: A perceptually-driven still picture codec”, IEEE ICIP, Session MA.L3: Image compression grand challenge, Phoenix, AZ, Sept. 2016.

DAALA-P1 Implement and improve Daala video codec using video test sequences and compare with HEVC/H.264/VP9 and other standard based codecs using implementation complexity, PSNR, SSIM, BD-bit rate and BD-PSNR as the metrics. See {DAALA1 and DAALA3].

DAALA-P2 Performance comparison of SDCT with DCT and DDCT is investigated in [E392]. In DAALA INTDCT is used. Replace INTDCT with INTSDCT and implement the performance comparison based on various test sequences including 4K and 8K and different block sizes. See the Tables and Figures in [E392].


DAALA-P3

See [E393]. Apply the FCDR to DAALA video codec both as a post processing operation and as an in loop (embedded) operation. Implement the projects for DAALA similar to those described in P.5.268 and P.5.269.
