Theta expand


This operation must be used in tandem with Double peaks clean-up operation in the peak positioning post-operations.

This operation expands the right side of the HoughMap pass 180 deg. No new Hough transform is performed. The \Delta\theta and \Delta\rho resolution are unaffected. The expansion duplicates and rearranges the information present on the left side of the HoughMap.


This operation takes one parameter: the angular increment to add on the right side of the HoughMap. In other words, by how many degrees the original \theta range of the HoughMap (0 to 180 deg) must be extended.
