License Plate Blur API

Detects and localizes license plates numbers on vehicles and blurs it from a still input photo.

License Plate blur API - PlateBlurer (also known as LPTR API or ALPTR API) is a cross browsers REST API which get a JSON input with a still photo (as base64 encoded string), containing vehicles with registrations plates and returns a JSON string which contains a base64 encoded string photo with blured plate(s), confidence score, timestamp, vertices for bounding boxes of license plates. Of course, there are some limitations in order to get a higher accuracy. We recommend properly exposed, unobstructed JPEG photos at 1920x1080 (full HD resolution) where ratio between height of the license plate and height of entire picture should be at least 1:15. For ratios like 1:16, 1:17, 1:18 and so on the accuracy is lower and the AI algorithm may not see and read the license plate and the number on the registration plate. We do not store pictures. Also, the quality and the angles of the LPR camera are very important and it contribute to a higher reading accuracy. It should have varifocal lenses, high shutter speed, good infrared lighting beam, full HD resolution. 

Allthough this Automatic Plate blur API (currently we do not offer a license plate blur sdk) is intended for software development and therefore developers, we have also here an license plate blur online application that may be used to check the input and output JSONs of the API. The necessary steps are written below, basically for this real time license plate blur API you send an authorized POST request in JSON format to the API endpoint and you get as JSON response the output as described below through parameters and examples.

This Number Plate Blur API is useful for a large number of domains like: vehicles anonymizers apps, virtual tours, Google Street View panos etc.You own the commercial copyright of the resulted JSON with no additional fee meaning you may use it in your own apps for sale.
