License Plate Recognition Pipeline

Design an end-to-end Automatic License Plate Recognition (ALPR) system for a parking garage.

Scenario: A parking garage needs to automatically read license plates of entering vehicles. The system must work with varying lighting conditions, angles, and plate formats.

Your Task: Design the complete pipeline from raw camera input to recognized plate text.

Key Challenges to Address:

Vehicle and plate detection in the frame
Plate localization and perspective correction
Character segmentation and recognition
Handling different plate formats and conditions

Your design should handle: Motion blur, varying illumination, different plate colors, and partial occlusions.
