# Introduction

**degirum-vehicle** is a high-performance Python library for License Plate Recognition (LPR) and vehicle analytics in images and video. Built for production deployments with minimal code and support for CPU and edge AI accelerators. Code examples and usage tutorials are available in the [DeGirum Vehicle Analytics repo](https://github.com/DeGirum/vehicle_analytics).

**Fast and efficient** vehicle analytics with:

* License plate detection, text recognition, and tracking for images, video files, and live streams
* **Multi-hardware support**: CPU, GPU, and edge AI accelerators - see [supported hardware](https://docs.degirum.com/vehicle-analytics/getting-started/basic-concepts#what-hardware-is-supported)
* **Simple APIs**: Minimal code to detect, track, and recognize license plates with easy batch processing
* **Flexible configuration**: Python or YAML config for models, thresholds, and tracking parameters
* **Production-ready tracking**: Real-time vehicle tracking, Bayesian text aggregation, and event notifications
* **Robust recognition**: Multi-frame text aggregation for improved accuracy
