Fourier Angle Transformation of Picture, C++

271 Views Asked by At

I need get angle of object on picture, using Fourier transformation.

I have a picture object, that I rotated. There are no problems with the Fourier realization. It shows me good gradient lines that confirm the correct object angle.

Q. How do I get angle points from the Fourier gradient, to transform it horizontally?

You don't show us the image or its transform, so I'll assume the gradient lines are indeed clear enough. In that case you'd use the Hough transform. Output is a set of lines, each with an angle.
