This function is almost identical with the function `get_line_lens()` defined in the previous subsection. The only
difference being the last argument of the function. The routine
returns a map (`out_img`) whose pixels have the value of either
unity if the pixel corresponds to a line point and zero otherwise.

Author: Warren G. Anderson, warren@ricci.phys.uwm.edu This routine is an interface to the routines by Carsten Steger to detect one dimensional structures in two dimensional images, [34,35].
