Optimizing Model with Dynamic Input Shape using Intel® Distribution of OpenVINO™ Toolkit for Implementing Unconstrained Automatic License Plate Recognition - Technical Paper

Last Updated: Mar 12, 2025

This document introduces the BKM for optimizing and implementing the unconstrained automatic license plate recognition (ALPR) using OpenVINO™ Toolkit 2022.1. Unlike the conventional methods, the unconstrained ALPR can detect distorted license plates (LPs) captured at non-frontal views. It is achieved by resizing the input vehicle image according to its aspect ratio before being fed to the license plate detection model.
