Hello.I'm new by opencv and I do not know programming with c or c++,so excuse me if my question is weak and it's answer is obvious.Of course,before I ask this question,did a lot searching in Google,opencv Q\A and stackoverflow,but unfortunately I do not found answer.

I have to change brightness and contrast of a bitmap.I know how to get a Mat form bitmap in android.But I could not find any method in Imageproc class to change contrast and brightness of bitmap.Is there any way in java (without using native codes) to do those processes?
