|Research Topics of the Image & Video Coding Group|
|Selected Research Projects|
|High Efficiency Video Coding (HEVC)|
contributed significantly to the development of the basic architecture
of the video coding layer of the upcoming High Efficiency Video Coding
(HEVC) standard. Several new coding tools have been developed and
successfully contributed as part of the novel specification.
|HEVC Extension for 3D Video Coding|
developing an extension of HEVC for 3D video coding that supports the
coding of multiple views and associated depth data. It adds new coding
tools to the HEVC design, which improve the compression capabilities for
dependent video views and depth data.
contributed significant parts of the basic video coding layer of the
first, basic version of H.264/MPEG-4 AVC. These parts include
motion-compensated prediction, tree-structured picture partitioning,
entropy coding and rate-distortion optimized encoder control.
|Scalable Video Coding (SVC) Extension of H.264/MPEG-4 AVC|
developed an extension of H.264/MPEG-4 AVC that provides the support of
different types of scalability at a bitstream level with only a moderate
increase in decoder complexity. This Scalable Video Coding (SVC)
extension allows on-the-fly adaptation of bit rate, format, and power
consumption as well as graceful degradation in lossy transmission
|Multiview Video Coding (MVC) Extension of H.264/MPEG-4 AVC|
developed a simple, but very efficient approach for multiview video
coding as an extension of H.264/MPEG-4 AVC. This extension does not
include any changes of the basic decoding process and requires only a
modification of the high-level syntax of H.264/MPEG-4 AVC.
|Fidelity Range Extension (FRExt) of H.264/MPEG-4 AVC|
developed and contributed a design for the support of 8x8 transforms and
8×8 intra prediction modes in H.264/MPEG-4 AVC. This basic architecture
was adopted as the basis for the development of FRExt, in particular the
High Profile of H.264/MPEG-4 AVC.
|Rate-Distortion Optimized Encoding|
|We are very
active in optimizing the encoder control for different video coding
standards. The investigated encoder control concepts have become an
integral part of the reference model and reference software for the
video coding standards H.264/MPEG-4 AVC and HEVC.
|Statistical Coding & Modeling|
developing efficient methods for statistical modeling and coding with a
particular focus on application in video coding. Our research includes
the topics of fast binary arithmetic coding, context modeling,
probability estimation, and binarization. In addition, we are
investigating the concept of probability interval partitioning entropy
(PIPE) codes as a low complex, but yet highly efficient variant of
binary arithmetic coding.
|Wavelet-Based Image & Video Coding|
developed hybrid video coding schemes that are based on the combination
of motion-compensated prediction and wavelet-based transform coding.
