SimpleLPR is a software component for vehicle license plate recognition. It has a very simple programming interface that allows applications to supply a path to an image or a buffer in memory and return the detected license plate text and its location in the input image. It can be used from C++, .NET-enabled programming languages, or Python. Integration is simple and straightforward, as demonstrated by the examples provided with the SDK. Typical detection rates range between 85% and 95%, provided the license plates are in good condition, free of obstructions, and the text height is at least 20 pixels.

You can download the user's guide from https://www.warelogic.com/doc/SimpleLPR3.pdf, and the class reference for .NET from https://www.warelogic.com/doc/SimpleLPR.chm.

Code example:
	
using System;
using System.Collections.Generic;
using SimpleLPR3;	
	
// Create an instance of the SimpleLPR engine
EngineSetupParms setupP;
setupP.cudaDeviceId = -1; // Select CPU
setupP.enableImageProcessingWithGPU = false;
setupP.enableClassificationWithGPU = false;
setupP.maxConcurrentImageProcessingOps = 0;  // Use the default value

// Create the SimpleLPR engine
ISimpleLPR lpr = SimpleLPR.Setup(setupP);

// Enable country templates for Brazil
lpr.set_countryWeight("Brazil", 1.0f);
lpr.set_countryWeight(countryId, 1.0f);

// Create a processor object
IProcessor proc = lpr.createProcessor();

// Use the analyze version that takes the path to a file
List<Candidate> cds = proc.analyze("image.jpg");

// Iterate over all candidates
foreach (Candidate cd in cds)
{
   // Iterate over all country matches
   foreach (CountryMatch match in cd.matches)
   {
       Console.WriteLine("Text: {0}, country: {1}", match.text, match.country);
   }
}
