Hi, I am a student and am doing my final year project on Number plate
recognition. I would really appreciate if someone could provide me
with the source code. Thx in advance

This topic came up less than two weeks ago. Rather than re-writing
the suggestions posted at that time, I'll just copy-and-paste the
clearest advice from that previous thread, which was:

   Don't be silly. You can't use car plates to keep track of hippopotami:
   the mud gets all over the plates and renders them useless. Everyone
   in the field knows that you have to use bar-codes! [...]

   The only hard part is training the Labeo fish to carry the
   bar-code reader close enough to the hippos for a solid reading.

I am doing the same project, but i am stuck at the method to
use.If u have got the code plz share it with me.We can have
good conversation o this topic.
Thanks & regards.

have you figured out the mud on the plates problem?

Here is a good bit of Pucka gen to help you with this
problem.

1) Don't use ambient light to illuminate the number plate -
use a low pressure Sodium discharge lamp.

2) Put a narrow band optical filter in front of your camera
lens, which only passes the Dominant Sodium D lines from
your source.

3) The sun emits no radiation in the Sodium D lines as it
coincides with a Fraunhofer absorbtion line (The Sun
contains Sodium in its atmosphere!).

4) This way - subject to you having a narrow illumination
beam virtually removes all image clutter making it much
easier to identify the numberplate from other objects in
the scene.

5) Because you are supplying the illumination, and getting
nothing from the ambient light, your camera exposure is
fixed.

6) Its a good stunt for detecting sea skimming missiles to.

p.s. doesn't do anything for the Mud :-(

actually i want to know the good method for segmentation
or character recognition.
