OpenVX
OpenVX is an open, royalty-free standard for cross platform acceleration of computer vision applications. It is designed by the Khronos Group to facilitate portable, optimized and power-efficient processing of methods for vision algorithms. This is aimed for embedded and real-time programs within computer vision and related scenarios. It uses a connected graph representation of operations.

Overview
OpenVX specifies a higher level of abstraction for programming computer vision use cases than compute frameworks such as OpenCL. The high level makes the programming easy and the underlying execution will be efficient on different computing architectures. This is done while having a consistent and portable vision acceleration API.
OpenVX is based on a connected graph of vision nodes that can execute the preferred chain of operations. It is possible to optimize the underlying implementation through various techniques, for example: acceleration on various processing units or dedicated hardware. This architecture facilitate applications programmed in OpenVX on different systems with different power and performance, including battery-sensitive, vision-enabled, wearable displays.
OpenVX is complementary to the open source vision library OpenCV. OpenCV is also used for application prototyping, however it is not as tightly defined and does not have graph optimizations.
