Is there any function supported by opencv which make the Mellin transform and Fourier transform.
Thanks in advance.Wed, 20 Feb 2013 07:48:58 -0600http://answers.opencv.org/question/7749/mellin-transform/Answer by Mathieu Barnachon for <p>Hi,

I'm not aware of the Mellin transform in OpenCV, but if you have your own implementation, OpenCV is a free software, feel free to propose yours to add it...Wed, 20 Feb 2013 12:02:59 -0600http://answers.opencv.org/question/7749/mellin-transform/?answer=7765#post-id-7765Comment by berak for <p>All you want to know about Fourier in OpenCV is <a href="http://docs.opencv.org/doc/tutorials/core/discrete_fourier_transform/discrete_fourier_transform.html">here</a>.
