AMD OpenVX modules (amdovx-modules)

The OpenVX framework provides a mechanism to add new vision functions to OpenVX by 3rd party vendors. This project has below OpenVX modules and utilities to extend amdovx-core project, which contains the AMD OpenVX Core Engine.

• vx_nn: OpenVX neural network module
• model_compiler: generate efficient inference library from pre-trained models (such as ONNX)
• inference_generator: generate inference library from pre-trained CAFFE models
• annInferenceServer: sample Inference Server
• annInferenceApp: sample Inference Client Application
• vx_loomsl: Radeon LOOM stitching library for live 360 degree video applications
• loom_shell: an interpreter to prototype 360 degree video stitching applications using a script
• vx_opencv: OpenVX module that implemented a mechanism to access OpenCV functionality as OpenVX kernels

If you're interested in Neural Network Inference, start with the sample inference application.

Refer to Wiki page for further details.

Pre-requisites

• CPU: SSE4.1 or above CPU, 64-bit
• GPU: Radeon Instinct or Vega Family of Products (16GB recommended)
  • Linux: install ROCm with OpenCL development kit
  • Windows: install the latest drivers and OpenCL SDK download
• CMake 2.8 or newer download
• Qt Creator for annInferenceApp
• protobuf for inference_generator
  • install libprotobuf-dev and protobuf-compiler needed for vx_nn
• OpenCV 3 (optional) download for vx_opencv
  • Set OpenCV_DIR environment variable to OpenCV/build folder

Refer to Wiki page for developer instructions.

Build using CMake on Linux (Ubuntu 16.04 64-bit) with ROCm

• git clone, build and install other ROCm projects (using cmake and % make install) in the below order for vx_nn.
  • rocm-cmake
  • MIOpenGEMM
  • MIOpen -- make sure to use -DMIOPEN_BACKEND=OpenCL option with cmake
• git clone this project using --recursive option so that correct branch of the amdovx-core project is cloned automatically in the deps folder.
• build and install (using cmake and % make install)
  • executables will be placed in bin folder
  • libraries will be placed in lib folder
  • the installer will copy all executables into /opt/rocm/bin and libraries into /opt/rocm/lib
  • the installer also copies all the OpenVX and module header files into /opt/rocm/include folder
• add the installed library path to LD_LIBRARY_PATH environment variable (default /opt/rocm/lib)
• add the installed executable path to PATH environment variable (default /opt/rocm/bin)

Build annInferenceApp using Qt Creator

• build annInferenceApp.pro using Qt Creator
• or use annInferenceApp.py for simple tests

Build Radeon LOOM using Visual Studio Professional 2013 on 64-bit Windows 10/8.1/7

• Use loom.sln to build x64 platform
