HONG KONG -- November 18, 2013

The Khronos™ Group today  announced the ratification and public release of the
OpenVX™ 1.0 provisional specification, an open, royalty-free standard for
cross platform acceleration of computer vision applications and libraries.
OpenVX enables performance and power optimized computer vision algorithms for
use cases such as face, body and gesture tracking, smart video surveillance,
automatic driver assistance systems, object and scene reconstruction,
augmented reality, visual inspection, robotics and more. The provisional
release of the specification enables developers and implementers to provide
feedback before specification finalization, which is expected within six
months. The OpenVX 1.0 provisional specification is available at

“Computer vision is the biggest, most disruptive, application segment in
technology today. From automotive, to security, to consumer capture with 3D
sensors, 4K sensors, and sensors so small they can be put in UAVs the size of
a fly, the processing of photons has never been more challenging,” said Dr.
Jon Peddie, president of Jon Peddie Research. “Being able to manage, process,
and quickly move sensor data without consuming much power is critical and only
OpenVX offers the mechanisms necessary to balance all those issues - it’s
going to change the way we do vision systems.”

OpenVX enables significant implementation innovation while maintaining a
consistent API for developers. An OpenVX application expresses vision
processing holistically as a graph of function nodes. An OpenVX implementer
can optimize graph execution through a wide variety of techniques such as:
acceleration of nodes on CPUs, GPUs, DSPs or dedicated hardware, compiler
optimizations, node coalescing, and tiled execution to keep sections of
processed images in local memories as they flow through the graph. Khronos has
released a provisional tiled execution extension alongside the main OpenVX
specification to enable user custom kernels to exploit this style of
optimization. Additionally, Khronos has released the VXU™ utility library to
enable developers using OpenVX to call individual nodes as standalone
functions for easy code migration.

“Computer vision is central to bringing natural user interfaces and
environmental awareness to mobile devices and OpenVX enables cross-platform
processing with the high performance and low power that will be vital to
widespread adoption,” said Neil Trevett, president of the Khronos Group and
vice president of mobile content at NVIDIA. “OpenVX has been designed to be
implemented independently or to interoperate within the Khronos standards
ecosystem for camera control, sensor fusion, data flow, compute acceleration
and graphics rendering, ensuring Khronos APIs continue to meet the needs of
portable, state-of the art applications.”

OpenVX can be used directly by applications or to accelerate higher-level
middleware, such as the popular OpenCV open source vision library that is
often used for application prototyping. OpenVX will have extensive conformance
tests to complement a focused and tightly defined finalized specification for
consistent and reliable operation across multiple vendors and platforms making
OpenVX an ideal foundation for shipping production vision applications.
Finally, as any Khronos specification, OpenVX is extensible to enable nodes to
be deployed to meet customer needs, ahead of being integrated into the core

Industry Support

“The Itseez team is excited about the release of the OpenVX 1.0 provisional
specification. It will enable speed- and power-optimized implementations of
OpenCV across a wide range of mobile and embedded platforms, stimulating
growth for the computer vision industry and the development of new great
applications,” said Victor Erukhimov, CEO, Itseez and chair of the OpenVX
working group.

“CEVA extends its congratulations to the Khronos Group on the release of the
OpenVX 1.0 specification, which sets the foundation for mass market adoption
of computer vision applications across multiple industries,” said Eran Briman,
vice president of marketing at CEVA. “In particular, OpenVX directly addresses
the power consumption challenges faced when implementing complex vision
algorithms in power-sensitive products by enabling the seamless offload of
these tasks from the CPU and GPU onto dedicated vision engines, such as our
CEVA-MM3101 platform, resulting in significant power savings.”

“Going forward, vision systems will be a key differentiator for a wide range
of consumer products including smartphones, tablets, automotive driver
assistance and many more. Based on Imagination’s in-depth imaging expertise,
we are offering innovative PowerVR products for imaging and vision that will
enable our customers to integrate this functionality on the SoC We are pleased
to see Khronos taking a leading role in driving open standards for computer
vision. OpenVX 1.0 is an important starting point for accelerating creation
and adoption of a wide range of vision applications,” said Peter McGuinness,
director of multimedia technology marketing, Imagination Technologies.

“Movidius anticipates OpenVX will stimulate incredible innovation as it
enables cross-platform, scalable computer vision for mobile devices,” said
Remi El-Ouazzane, CEO of Movidius. “In combination with OpenVX capable
applications, Movidius’ computational imaging chipsets empower mobile
developers to deploy vision-based applications that were simply never possible

“videantis congratulates the Khronos Group on reaching this major milestone.
OpenVX enables efficient acceleration of computer vision algorithms, a key
technology driving new applications such as always-on camera applications,
gesture interfaces, and automotive driver assistance systems. We’re proud to
bring support for this new standard to our v-MP4000HDX scalable unified
video/vision processor architecture,” said Hans-Joachim Stolberg, CEO at

“The release of OpenVX 1.0 is a ground-breaking step that will accelerate mass
market adoption of computer vision applications in mobile, home, automotive,
and embedded products. The specification benefits developers and lays a
foundation for complex vision algorithms to be simplified and
power/performance/bandwidth optimized on OpenVX compliant hardware, enabling
novel uses of vision processing on any platform. Participation in the
workgroup has allowed us to make significant breakthroughs in our Vega GPUs to
streamline the visual processing pipeline from beginning to end,” said Wei-Jin
Dai, Vivante CEO.
