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.
