hough_circles- Detect centers of circles for a specific radius using the Hough transform.
hough_line_trans- Produce the Hough transform for lines within regions.
hough_line_trans_dir- Compute the Hough transform for lines using local gradient direction.
hough_lines- Detect lines in edge images with the help of the Hough transform and returns it in HNF.
