YOLOv8-OBB: Optimized for Qualcomm Devices

Ultralytics YOLOv8-OBB is a machine learning model that predicts oriented bounding boxes (OBB) and classes of objects in an image. It is designed for detecting objects that are not axis-aligned, such as aerial imagery or tilted text.

This is based on the implementation of YOLOv8-OBB found here. This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the Qualcomm® AI Hub Models library to export with custom configurations. More details on model performance across various devices, can be found here.

Qualcomm AI Hub Models uses Qualcomm AI Hub Workbench to compile, profile, and evaluate this model. Sign up to run these models on a hosted Qualcomm® device.

Getting Started

Due to licensing restrictions, we cannot distribute pre-exported model assets for this model. Use the Qualcomm® AI Hub Models Python library to compile and export the model with your own:

  • Custom weights (e.g., fine-tuned checkpoints)
  • Custom input shapes
  • Target device and runtime configurations

See our repository for YOLOv8-OBB on GitHub for usage instructions.
