# License-Plates-Detector-Model: Optimized for Qualcomm Devices
A YOLOv8-nano object detection model fine-tuned on the UAE licence-plate dataset (Roboflow car-plate-k6xij v26). The model detects and classifies 51 object classes: digits 0-9, letters A-Z, UAE emirate region identifiers and a plate bounding-box class for the full plate region.
This is based on the implementation of License-Plates-Detector-Model found [here](https://github.com/3bdul1ah/License-Plates-Detector-Model).
This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/v0.66.0/src/qai_hub_models/models/lpdm) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary).
Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) 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](https://github.com/qualcomm/ai-hub-models/blob/v0.66.0/src/qai_hub_models/models/lpdm) 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 [License-Plates-Detector-Model on GitHub](https://github.com/qualcomm/ai-hub-models/blob/v0.66.0/src/qai_hub_models/models/lpdm) for usage instructions.
