I would like to plot a 3D graph from it, the row as x-axis, column as y-axis & the pixel values on each coordinate(row,column) as z-axis. I would like to plot the graph similar to the surf function in Matlab.

http://answers.opencv.org/question/113583/3dplot-library-c-c-in-opencv/?answer=113585#post-id-113585short answer: no.
(longer one, have a look at the [plot](https://github.com/opencv/opencv_contrib/tree/master/modules/plot) module, expand it's functionality to 3d, and contribute !) Wed, 16 Nov 2016 10:16:09 -0600http://answers.opencv.org/question/113583/3dplot-library-c-c-in-opencv/?answer=113585#post-id-113585
