MIVisionX toolkit is a set of comprehensive computer vision and machine intelligence libraries, utilities, and applications bundled into a single toolkit. AMD MIVisionX delivers highly optimized conformant open-source implementation of the Khronos OpenVX™ and OpenVX™ Extensions along with Convolution Neural Net Model Compiler & Optimizer supporting ONNX, and Khronos NNEF™ exchange formats. The toolkit allows for rapid prototyping and deployment of optimized computer vision and machine learning inference workloads on a wide range of computer hardware, including small embedded x86 CPUs, APUs, discrete GPUs, and heterogeneous servers.

Latest release

AMD OpenVX™

AMD OpenVX™ is a highly optimized conformant open source implementation of the Khronos OpenVX™ 1.3 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.

Khronos OpenVX™ 1.0.1 conformant implementation is available in MIVisionX Lite

AMD OpenVX™ Extensions

The OpenVX framework provides a mechanism to add new vision functionality to OpenVX by vendors. This project has below listed OpenVX modules and utilities to extend amd_openvx, which contains the AMD OpenVX™ Core Engine.

• amd_loomsl: AMD Loom stitching library for live 360 degree video applications
• amd_media: AMD media extension module is for encode and decode applications
• amd_migraphx: AMD MIGraphX extension integrates the AMD's MIGraphx into an OpenVX graph. This extension allows developers to combine the vision funcions in OpenVX with the MIGraphX and build an end-to-end application for inference.
• amd_nn: OpenVX neural network module
• amd_opencv: OpenVX module that implements a mechanism to access OpenCV functionality as OpenVX kernels
• amd_rpp: OpenVX extension providing an interface to some of the ROCm Performance Primitives (RPP) functions. This extension enables rocAL to perform image augmentation.
• amd_winml: AMD WinML extension will allow developers to import a pre-trained ONNX model into an OpenVX graph and add hundreds of different pre & post processing vision / generic / user-defined functions, available in OpenVX and OpenCV interop, to the input and output of the neural net model. This extension aims to help developers to build an end to end application for inference.

Applications

MIVisionX has several applications built on top of OpenVX modules. These applications can serve as excellent prototypes and samples for developers to build upon.

Neural network model compiler and optimizer

Neural net model compiler and optimizer converts pre-trained neural net models to MIVisionX runtime code for optimized inference.

rocAL

The ROCm Augmentation Library - rocAL is designed to efficiently decode and process images and videos from a variety of storage formats and modify them through a processing graph programmable by the user.

rocAL is now available as an independent module at https://github.com/ROCm/rocAL. rocAL is deprecated in MIVisionX.

Toolkit

MIVisionX Toolkit is a comprehensive set of helpful tools for neural net creation, development, training, and deployment. The Toolkit provides useful tools to design, develop, quantize, prune, retrain, and infer your neural network work in any framework. The Toolkit has been designed to help you deploy your work on any AMD or 3rd party hardware, from embedded to servers.

MIVisionX toolkit provides tools for accomplishing your tasks throughout the whole neural net life-cycle, from creating a model to deploying them for your target platforms.

Utilities

• loom_shell: an interpreter to prototype 360 degree video stitching applications using a script
• mv_deploy: consists of a model-compiler and necessary header/.cpp files which are required to run inference for a specific NeuralNet model
• RunCL: command-line utility to build, execute, and debug OpenCL programs
• RunVX: command-line utility to execute OpenVX graph described in GDF text file
