Automatic License Plate Recognition System Using Computer Vision in MATLAB and Simulink

Rionel Caldo · 5 months ago

The short version: A MATLAB/Simulink tutorial by Rionel Caldo shows how trivial it's become to build license-plate recognition from scratch, underscoring how little barrier stands between any coder and mass surveillance.

Our Take

Rionel Caldo's walkthrough is aimed at students and engineers learning computer vision, not at building a surveillance dragnet — but that's exactly why it's worth watching. When plate-reading software can be assembled with off-the-shelf MATLAB toolboxes and a few hours of tutorial time, it's a reminder that the 'advanced technology' behind companies like Flock Safety isn't some impenetrable black box. It's commodity computer vision, packaged, marketed, and sold as a subscription service to police departments and HOAs.

That gap between technical simplicity and deployment scale is the real story. The hard part was never reading a plate — it's networking thousands of cameras together, archiving the hits, and sharing them across jurisdictions without a warrant. Tutorials like this one make the underlying mechanics legible, which is useful, but they also show how quickly this capability can proliferate beyond any single vendor's control once the code is out there.

We think the public conversation should focus less on the novelty of the algorithm and more on who's pointing these cameras at your street and what happens to the data afterward. Check our camera map to see what's been deployed near you, and visit take-action if you want to push back on unchecked ALPR expansion in your community.
