MIVisionX

MIVisionX toolkit is a set of comprehensive computer vision and machine intelligence libraries, utilities, and applications bundled into a single toolkit. AMD MIVisionX also delivers a highly optimized open-source implementation of the Khronos OpenVX™ and OpenVX™ Extensions.

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.

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
