I know we can set all pixel values, and access each pixel to set values. Suppose I already have a set of pixels, whose value alone, I want to set as say 255. Is this possible, in opencv? Is there a function can do this? Sorry if this question is rudimentary

  • I think the asnwer given was something I was looking for. I already know how to access elements, as I had mentioned @pwwpche – Lakshmi Narayanan Apr 26 '15 at 23:33
  • [This](http://stackoverflow.com/questions/8971308/what-is-cvsetto-function) gives a better explanation on how to use the function as well. – Lakshmi Narayanan May 02 '15 at 09:27

Check out the setTo function, which allows to set the value of some masked mat elements:

Mat& Mat::setTo(InputArray value, InputArray mask=noArray() )
