Release Notes for STM32N6-GettingStarted-ObjectDetection Application

Purpose

Object Detection application to enable the deployment of object detection models on STM32N6570-DK and NUCLEO-N657X0-Q boards.

This application is prebuilt with an object detection model.

Key Features

  • Sequential application flow
  • NPU accelerated quantized AI model inference
  • Dual DCMIPP pipes
  • DCMIPP crop, decimation, downscale
  • DCMIPP ISP usage
  • LTDC dual-layer implementation
  • Dev mode
  • Boot from External Flash
