Clear image reflections for character recognition
3 posts
• Page 1 of 1
Clear image reflections for character recognitionI am developing an optical character recognition system with image processing. Unfortunately, there is glass protection in front of the image. Therefore, I encounter reflections and light problems, is there any way I can avoid light and reflection problems.

Re: Clear image reflections for character recognition
Most of the time it is solved with proper light sources - i.e. special lighting is used to avoid reflection issues. Trying to solve it with image processing is not trivial, if not achievable. You may always get a different case where your algorithm fails.

Thank you for your answer. You're right, I need proper lighting.
