JavaANPR is not recognizing plates as it should?
In situations like these, the report generator can often help.
You can run it from the executable jar with
java -jar javaanpr.jar -recognize -i path_to_your_image.jpg -o report_directory/
or mvn exec:java -Dexec.args="-recognize -i path_to_your_image.jpg -o report_directory/".
From the report (image courtesy of walterog19)
we can see that it (incorrectly) fixates on the brake lights,
instead of on the plate in such a sunny and bright image.
One solution is to crop them out (see image on the right).
JavaANPR then detects the plate "TSZ452" with a correct syntax.xml setting, which is almost correct.
As to what you can do about it generally (without cropping) — you could try some pre-processing, for example lessening the brightness, normalizing the picture, etc… For example, using a threshold filter for brightness 250-255, I got the correct result: (not saying this is what you want to do in general, it depends on the camera, lighting, …)
