Image extraction in C

P: 1
Hi all, actually i'm now doing something on license plate recognition system for my project. The first step would be the license plate extraction algorithm which means it is needed to extract a license plate from an image captured. So, i wonder how can this be done? Actually i'm thinking of something like detect the image pixels of the license plate since the license plate that i'm gonna work on at this stage is black and white in color. So that means i need to at least detect the black and white pixels. My question is

-is there any functions in C library that will support the detection of colors(in this case black and white)?and what are those functions? Preferably given the syntax here with examples.

-what other things i need to detect to improve the accuracy of the license extraction algorithm?

Your help is greatly appreciated.

You should look into image processing. Check out how images are stored in memory. What is the image type you want, bmp, jpg, etc. And check how colors/ single pixels are represented in those image types. That is, if u r working with an image file. if u r reding right from the camera or something, u'll have to work on it.

You'd probably want to read up on neural networks as well. As far as I know, they are used in such applications.
