OpenALPR is an open source Automatic License Plate Recognition library written
in C++. The library analyzes images and identifies license plates. The output
is the text representation of any license plate characters found in the image.
The OpenALPR utils package contains a collection of binaries that help with
training new data.  The following binaries are included:
openalpr-utils-calibrate - Calibrates the software for cameras capturing plate
images at an angle
openalpr-utils-benchmark - Benchmarks accuracy/speed against a testing dataset
openalpr-utils-tagplates - Utility to tag the location and plate number for
testing and training
openalpr-utils-classifychars - Extracts character images from cropped plate
images for OCR training
openalpr-utils-prepcharsfortraining - Reformates character images into a format
that Tesseract can use for OCR training
