Today The Khronos Group announces a significant expansion in the ecosystem for the NNEF™ (Neural Network Exchange Format) open, royalty-free standard that enables hardware manufacturers to reliably exchange trained neural networks between training frameworks and inference engines. New and improved NNEF open source convertors, including for TensorFlow Lite and ONNX, enables NNEF to be used to carry trained frameworks from a wider range of training frameworks. A set of extensions to the NNEF 1.0 specification enable NNEF files to contain a richer network of operations and topologies. Finally, an openly available NNEF Model Zoo enables inferencing engines to test their reliable import of NNEF models. More information on NNEF can be found at the NNEF Home Page.

All of the presentations and videos from the Khronos OpenVX workshop at the 2019 Embedded Vision Summit are now online. If you were unable to attend this workshop, you may now watch the seven sessions online and follow along with the slide presentations:

  • Introduction and OpenCL Overview & Update – Neil Trevett, NVIDIA: slides, video
  • OpenCL & SYCL – Andrew Richards, Codeplay: slides, video
  • Intel Open Source SYCL Compiler Project – Konstantin S. Bobrovsky, Intel: slides, video
  • OpenVX Presentations – Frank Brill, Cadence / Niclas Danielsson & Mikael Pendse, Axis : here & here, video
  • Inference with OpenVX – Mike Schmit, AMD: slides, video
  • NNEF Presentation – Gergely Debreczeni, AImotive: slides, video
  • OpenVX Hands-On - Part 1 – Rajy Rawther & Kiriti Nagesh Gowda, AMD: slides, video

Codeplay Software has announced the availability of this fully supported edition of their popular SYCL implementation providing advanced features and premium technical support to developers seeking to bring advanced vision and AI products to the market. The first releases will support Intel GPUs and Renesas R-Car products, with other platforms becoming available soon.

Cadence Design Systems and ArcSoft announced they have partnered to develop AI and vision applications for Cadence Tensilica Vision DSPs. ArcSoft has collaborated with Cadence to port beauty shot, high dynamic range (HDR), bokeh and facial unlock applications to the Vision P6 DSP. The software environment includes complete, optimized support for more than 1,500 OpenCV-based vision and OpenVX 1.1 library functions.

The Khronos Group is accepting proposals for an OpenVX project. The project will deliver a fully conformant implementation of the OpenVX 1.2.1 standard that is optimized for the Raspberry Pi 3 Model B+ (or similar) platform. The project will demonstrate the performance advantage of using the OpenVX API by implementing several optimizations that are enabled by OpenVX. Deadline for submissions is January 15, 2019. Complete details here.

Percepio Tracealyzer for OpenVX allows you to visualize the execution of OpenVX applications and identify bottlenecks where optimization can make a big difference. Tracealyzer for OpenVX is initially available for Synopsys EV6x embedded vision processors, leveraging the built-in trace support in Synopsys ARC MetaWare EV Development Toolkit. Percepio Application Note PA-025 describes how to get started with Tracealyzer for OpenVX, using Synopsys EV6x processors and Synopsys MetaWare EV Development Toolkit.

Neil Trevett, President of the Khronos Group, delivers the presentation “Update on Khronos Standards for Vision and Machine Learning” at the Embedded Vision Alliance’s September 2018 Vision Industry and Technology Forum. Neil Trevett shares updates on recent, current and planned Khronos standardization activities aimed at streamlining the deployment of embedded vision and AI. For the full version of this video, along with hundreds of others on various embedded vision topics, please visit the Embedded Vision website.

NXP delivers a wide range of processing solutions on which machine-learning (ML) applications can run. Developers will need the associated software and tools to make them work and this is where eIQ framework and development tools come into play. The eIQ framework is designed to work with hardware abstraction layers like OpenCL, OpenVX, and the Arm Compute Library, as well as inference engines like the Arm NN (neural net), Android NN, GLOW, and OpenCV.

Khronos member Peter McGuinness has written an overview about NNEF over on the GFXSpeak blog. The new standard was released in provisional form in December of 2017 and, after a period of consultation with industry, is now ratified in its final form and available for immediate use. As well as the standard itself, Khronos is simultaneously releasing a suite of open source tools to allow developers to immediately begin using the format with the three most popular training frameworks: Tensorflow and Caffe/Caffe2. All of these tools are available on GitHub in the Khronos repo. Learn more about NNEF.

OpenVINO is a comprehensive toolkit for developing applications and solutions that emulate human vision. Based on Convolutional Neural Networks (CNNs), the toolkit extends CV workloads across Intel hardware, maximizing performance. OpenVINO enables CNN-based deep learning inference on the edge; supports heterogeneous execution across computer vision accelerators—CPU, GPU, Intel Movidius Neural Compute Stick, and FPGA—using a common API; and includes optimized calls for OpenCV and OpenVX.
