AMDOVX is short for AMD OpenVX as an open-source implementation of the Khronos Group's OpenVX computer vision specification. AMDOVX works on both x86 CPUs and GPUs via OpenCL. AMDOVX is supported on both Windows and Linux while providing interoperability with OpenCV. This open-source code does depend upon the AMD APP SDK 3.0 release.
Details on the new AMD OpenVX implementation can be found via GPUOpen.com while the newly-opened code (marked as v0.9 beta) was open-sourced this week to this GitHub repository.
