Hi, I can do this project for you. Hough Transform, edge detection and alike are pretty easy subjects for me. I have ever even implemented the Circle Hough Transform, so the line version would be very easy for me too. If you're interested, PM and I can show it to you. By the way if you're not very confident about awarding me the project we could do the following: I do the project and I will send you the .exec file, so you can see it working. All that WITHOUT you AWARD me the project, but If you like the results, you award me the project and I will immediately send you the source code.
