I have done various image processing. I have done captcha solving, face recognition and similar stuff. I can develop this. Will only need few more sample images, a round number 100 should do it. I will write my own code, without use any third party plugins, libraries, anything that would mean any licence. Code will be without any licence, you will get complete source code.
I can do it in C# or C, if you don't need GUI just the output log, C would be the fastest solution.
I can make a small POC example in few days, before you award me the project.
