InterDigital develops CompressAI platform to accelerate AI-based video compression research and development
September 16 2020 - 8:31AM
InterDigital, Inc. (NASDAQ:IDCC), a mobile and video technology
research and development company, today announced that it has
developed CompressAI, a software platform to simplify and
accelerate AI-based video compression research. CompressAI allows
researchers to quickly design, train, test, and evaluate AI-based
codecs. The open source platform, recently released to the video
compression research and standards communities, is already being
used to support the development of next generation image and video
codecs.
Research teams around the globe are examining how AI-based
approaches, in particular deep learning and neural networks, can be
used in the next generation of image and video codecs. However, the
process to complete AI-based video compression research often
includes several tedious and time consuming steps. Researchers who
invent a new neural network component or architecture must
typically augment this component with other neural network layers
to make a fully functioning image or video compression network,
then find image and video sequences with which to train their
network, and compare the results with existing compression
standards. Moreover, this process must be repeated every time a
team develops a new AI-based codec to evaluate.
Leveraging more than two decades of experience in video
compression and the independent research of InterDigital’s AI Lab,
CompressAI automates a large proportion of this research process to
accelerate the development and evaluation of candidate neural
network architectures in deep video compression research. The
CompressAI platform features the following software modules:
- Data loader: Loads data used to train neural
networks. The data loader includes pointers to several publicly
available data sets that can be used for training purposes.
- Data formatting: Translates and formats
training data (which is made of images and video segments stored in
a wide variety of file formats and binary representations) into a
simple representation which can easily be understood by neural
networks.
- Reference layers: Includes high-performance
implementation of several types of specialized neural network
layers used in video coding, such as layers that implement entropy
coding or generalized divisive normalization.
- Pretrained models: Includes implementations
developed by InterDigital, as well as downloadable pretrained
weights of several (already published) state-of-the-art neural
networks for deep image and video compression.
- Benchmarking: Compares the performance of both
traditional and deep learning-based codecs using well known
objective metrics such as PSNR (Peak Signal to Noise Ratio) or SSIM
(Structural Similarity Index Measure).
“The inexorable rise of rich media and high-quality video
streaming is putting significant strain on our networks, which
means continually improving codecs’ compression capabilities is a
must. Many research teams across the world are now looking at the
role of AI-based codecs and are developing and evaluating new
potential standards to meet the ever-growing demands for video
content. But developing these AI-based codecs involves several
complex, time-consuming and tedious steps,” said Jean Bolot, Vice
President of the AI Lab at InterDigital. “InterDigital has
developed the CompressAI platform to simplify and speed up the
process of deep video compression research, allowing teams to test
and evaluate AI-based codecs quickly and accurately. By making our
platform publicly available, we hope to be able to support the
incredibly important work research teams are doing to bring the
next generation of video compression standards.”
The Compress AI platform has been open sourced with an Apache v2
license and it is already being used by research teams across the
globe. It is publicly available on Github at:
