MIVisionX samples using OpenVX and OpenVX extensions. In the samples below we will learn how to run computer vision, inference, and a combination of computer vision & inference efficiently on target hardware.
- C/C++ Samples for OpenVX and OpenVX Extensions
- GDF - Graph Description Format Samples
- Loom 360 Stitch - Radeon Loom 360 Stitch Samples
- Model Compiler Samples - Run Efficient Inference
- MIVisionX Inference Deploy Samples
MIVisionX samples using RunVX
Note:
- To run the samples we need to put MIVisionX executables and libraries into the system path
export PATH=$PATH:/opt/rocm/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/rocm/lib
- To get help on RunVX, use
-hoption
runvx -h
usage:
runvx gdf/skintonedetect.gdf
usage:
runvx gdf/canny.gdf
Using a live camera

In this sample, we will learn how to run inference efficiently using OpenVX and OpenVX Extensions. The sample will go over each step required to convert a pre-trained neural net model into an OpenVX Graph and run this graph efficiently on any target hardware. In this sample, we will also learn about AMD MIVisionX which delivers open-source implementation of OpenVX and OpenVX Extensions along with MIVisionX Neural Net Model Compiler & Optimizer.
This sample shows how to run video decoding and object detection using pre-trained YoloV2 Caffe Model
The sample demonstrates the use of mv_compile utility to do video decoding and inference.
