Help for working with image

Hello,

I'm doing work for college and need to find a license plate on a picture of a car.
Does anyone have any material on this in JAVA? Or something that can help me?
I need the same help, I am almost desperate.

Thank you anyway!!!

This isn't exactly trivial- what does the picture of a car look like? I find it a little hard to believe that the course just dropped this assignment into your lap without any other information.

You might want to start googling for image recognition software, but like I said, unless you're working with a very specific optimal image, this isn't going to be easy.

The image will always be of the front of the car and quality is rather good.

I did some research and it seems I'll need to make a calculation of the tonal variation of the image.

For that I will need to pass it to grayscale and then make this calculation. Where there is more tonal variation in an area of ​​100x30, more likely to be the license plate in the image.

But how? T_T

Which part of this are you confused about? You mentioned several processes here. Like I said, you might want to look for a third party library for image manipulation and recognition. Or you could consult the BufferedImage API for some useful functions for manipulating the pixel data yourself.

Got it.

I only know in theory, apply it all is that I'm not getting. So, if someone had already done something similar, would help me a lot.

But anyway, thank you.
