I can find passport or driver licence in gray images. I've done a lot of work like this before. Please check my profile for reviews. I'm a computer science professional with a PhD degree and extensive experience (over 20 years) in face recognition, computer vision software development, object tracking, object recognition, image analysis, object classification, machine learning. I write codes in Python with OpenCV and a number of other languages. One of my past positions was a Senior Scientist at the Dept. of Computer Science at Virginia Tech, one of the nation's top Computer Science departments. It would be my pleasure to work on your project. Please contact me to discuss the project objectives.
Just FYI, I own a small engineering consulting business registered in the state of Illinois. You could pay me as an individual freelancer or as a business, whichever suits you better.
