Summary

0010250: The Hough Transform filter computes the hough Transform in pixel coordinates and not in world coordinates

Description

The class itk::HoughTransform2DLinesImageFilter computes the hough transform of an image for line detection. The output is the Hough Map, which is a 2D image where the x axis represents the angle of the line wrt the horizontal, and the y-axis the distance of the closest point from the line to the origin. To be coherent with all itk Filters, this distance should be given in world coordinates, but it is given in pixel coordinates. Then, one should compute the line parameters in pixel coordinate and convert the result to world coordinates. This should be chganged to directly do all computations in world coordinates
