AMD OpenVX

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.

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 mentioned OpenVX modules and utilities to extend amd_openvx, which contains the AMD OpenVX Core Engine.

• amd_loomsl: AMD Radeon Loom stitching library for live 360 degree video applications
• amd_media: vx_amd_media is an OpenVX AMD media extension module for encode and decode
• 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 RPP's (Radeon Performance Primitives) functions. This extension is used to enable rocAL to perform image augmentation.
• amd_winml: 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 will allow developers to build an end to end application for inference.

Applications

MIVisionX has several applications built on top of OpenVX modules, it uses AMD optimized libraries to build applications that can be used to prototype or use as a model to develop products.

• Bubble Pop: This sample application creates bubbles and donuts to pop using OpenVX & OpenCV functionality.
• Cloud Inference Application: This sample application does inference using a client-server system.
• Digit Test: This sample application is used to recognize hand written digits.
• Image Augmentation: This sample application demonstrates the basic usage of rocAL's C API to load JPEG images from the disk and modify them in different possible ways and displays the output images.
• MIVisionX Inference Analyzer: This sample application uses pre-trained ONNX / NNEF / Caffe models to analyze and summarize images.
• MIVisionX OpenVX Classsification: This sample application shows how to run supported pre-trained caffe models with MIVisionX RunTime.
• MIVisionX Validation Tool: This sample application uses pre-trained ONNX / NNEF / Caffe models to analyze, summarize and validate models.
• MIVisionX WinML Classification: This sample application shows how to run supported ONNX models with MIVisionX RunTime on Windows.
• MIVisionX WinML YoloV2: This sample application shows how to run tiny yolov2(20 classes) with MIVisionX RunTime on Windows.
