OpenVX & Neural Networks Workshop at Embedded Vision Summit - final curriculum now online

• Tags: Tutorials OpenVX embedded NNEF workshop Neural Networks Computer vision Vision


The curriculum for the 2018 OpenVX Workshop at the Embedded Vision Summit in May has been finalized. The Khronos Group will be presenting a day-long hands-on workshop all about OpenVX cross-platform neural network acceleration API for embedded vision applications. Khronos has developed a new curriculum making this a do-not-miss tutorial with new information on computer vision algorithms for feature tracking and neural networks mapped to the graph API. The tutorials will be presented by speakers from Khronos member companies AMD, Axis Communications, Cadence and Codeplay. There will be hands-on practice sessions with the folks who created the OpenVX API to give participants a chance to solve real computer vision problems. Discussions will also include the OpenVX roadmap and what’s to come. Registration is now open but space is limited, so be sure not to wait too long.

Khronos Group and Au-Zone Technologies to Develop Open Source TensorFlow and Caffe2 Converters for NNEF

• Tags:

The Khronos Group is working with Au-Zone Technologies to enable NNEF (Neural Network Exchange Format) files to be easily used with leading machine learning training frameworks. NNEF enables the optimized ingestion of trained neural networks into hardware inference engines on a diverse range of devices and platforms. Au-Zone is working with the Khronos NNEF Working Group to implement two purpose-built bidirectional converters, between TensorFlow and NNEF and also Caffe2 and NNEF. Both converters are expected to be released as open source projects to the development community in Q3 2018 under the Apache 2.0 license. Additionally, the NNEF and OpenVX Working Groups are working closely within Khronos to develop open-source importers, using the OpenVX Kernel Import extension, to enable the ingestion and execution of NNEF files.

Compressonator v3.0 brings powerful new 3D Model features for OpenGL and Vulkan

• Tags: glTF Vulkan OpenGL

Compressonator is a set of tools that allows artists and developers to work easily with compressed assets and easily visualize the quality impact of various compression technologies. Compressonator allows users to choose from all major compression formats for their texture files and supports DirectX® 12, Vulkan® and OpenGL®. Users can view OBJ files in OpenGL and GLTF with DirectX 12. Version 3.1 will support viewing GLTF 2.0 files using a choice of OpenGL, Vulkan or DirectX 12.
