Samples

Samples#

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.

GDF - Graph Description Format#

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 -h option

runvx -h

skintonedetect.gdf#

usage:

runvx gdf/skintonedetect.gdf

canny.gdf#

usage:

runvx gdf/canny.gdf

skintonedetect-LIVE.gdf#

Using a live camera

usage:

runvx -frames:live gdf/skintonedetect-LIVE.gdf

canny-LIVE.gdf#

Using a live camera

usage:

runvx -frames:live gdf/canny-LIVE.gdf

OpenCV_orb-LIVE.gdf#

Using a live camera

usage:

Loom 360 Stitch - Radeon Loom 360 Stitch Samples#

MIVisionX samples using LoomShell

Loom Stitch

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 loom_shell, use -help option

loom_shell -help

usage:

  • Get Data for the stitch

cd loom_360_stitch/sample-1/
python loomStitch-sample1-get-data.py

  • Run Loom Shell Script to generate the 360 Image

Model Compiler Samples - Run Efficient Inference#

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.

Sample-1: Classification Using Pre-Trained ONNX Model#

Sample-2: Detection Using Pre-Trained Caffe Model#

Sample-3: Classification Using Pre-Trained NNEF Model#

Sample-4: Classification Using Pre-Trained Caffe Model#

MV Object Detect Samples#

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.
