This module is developed from 「IoT Edge module extensions to be used with Azure Video Analyzer」 repository to be able to run on IoT Edge.

While running the IoT Edge module, you can use in conjunction with Azure Video Analyzer. It can be used as an inferencing server for HTTP extension node in Azure Video Analyzer on Edge. The performance of the YOLOv3 model inferencing server depends on the CPU power.

This module can be used with the Azure cloud native application WeDX Flow to simplify module management.

Minimum hardware requirements: Linux x64 and arm64 OS, 1GB of RAM, 950Mb of storage
