AMD OpenVX is a highly optimized open-source implementation of the Khronos OpenVX computer vision specification. It allows for rapid prototyping as well as fast execution on a wide range of computer hardware, including small embedded x86 CPUs and large workstation discrete GPUs.
The amd_openvx project consists of the following components:
- OpenVX: AMD OpenVX library
The OpenVX framework provides a mechanism to add new vision functions to OpenVX by 3rd party vendors. Look into amd_openvx_extensions for additional OpenVX modules and utilities.
- vx_loomsl: Radeon LOOM stitching library for live 360-degree video applications
- vx_nn: OpenVX neural network module that was built on top of MIOpen
- vx_opencv: OpenVX module that implemented a mechanism to access OpenCV functionality as OpenVX kernels
- vx_rpp: OpenVX extension providing an interface to some of the Radeon Performance Primitives (RPP) functions. This extension is used to enable RALI to perform image augmentation.
- vx_winml: OpenVX module that implemented a mechanism to access Windows Machine Learning(WinML) functionality as OpenVX kernels
- The code is highly optimized for both x86 CPU and OpenCL for GPU
- Supported hardware spans the range from low power embedded APUs, laptops, desktops, and workstation graphics
- Includes a “graph optimizer” that looks at the entire processing pipeline and removes/replaces/merges functions to improve performance and minimize bandwidth at runtime
- Scripting support allows for rapid prototyping, without re-compiling at production performance levels
- CPU: 64-bit SSE4.2 or above
- GPU: Radeon Professional Graphics Cards or Vega Family of Products (16GB required for vx_loomsl and vx_nn libraries)
Build this project to generate AMD OpenVX library
- Refer to openvx/include/VX for Khronos OpenVX standard header files.
- Refer to openvx/include/vx_ext_amd.h for vendor extensions in AMD OpenVX library
- Install OpenCV with/without contrib download for RunVX tool to support camera capture and image display (optional)
- OpenCV_DIR environment variable should point to OpenCV/build folder
- Use amd_openvx/amd_openvx.sln to build for x64 platform
- If AMD GPU (or OpenCL) is not available, set build flag ENABLE_OPENCL=0 in openvx/openvx.vcxproj and runvx/runvx.vcxproj
Build using CMake
- Install CMake 3.0 or later
- Use CMake to configure and generate Makefile
- If AMD GPU (or OpenCL) is not available, use build flag -DCMAKE_DISABLE_FIND_PACKAGE_OpenCL=TRUE
