  • I added example of image, I want to get image or without shade, or all shaded. Don't matter if result image will be black and white. – Karen Jun 24 '12 at 10:31

Following SOF might help you :

How to remove the shadow in image by using openCV?

There is a paper called "Simple Shadow Removal" in above link. Try to implement it.

  • This is good, but are there any library or implementation of this algorithms. – Karen Jun 24 '12 at 11:11
  • there are very few shortcuts i am afraid. mostly ppl need to code the stuff standard libraries do not provide. – AruniRC Jun 24 '12 at 12:11

    me too have that problem several times. Algorithm may be simple, but the people writing it wrap the algorithm in a set of complex mathematical equations and keywords, so that common people won't understand it. – Abid Rahman K Jun 24 '12 at 14:37
  • This should probably have been marked as *possible duplicate*, since the answer doesn't bring any extra relevant information. – karlphillip Jun 25 '12 at 00:28
  • Yeah, i knew it. In meantime , i was trying to implement any simple shadow removal algorithm and post it here, since this subject is always asked ( And i couldn't do it yet, due to above mentioned difficult keywords and equations in the paper) – Abid Rahman K Jun 25 '12 at 05:16
