<p class=MsoNormal><font size=2 face="Courier New"><span style='font-size:10.0pt;
font-family:"Courier New"'>Currently HoughTransform2DLinesImageFilter searches
between angles from –PI to PI but it does not provide a means to specify
the angle space? I felt that it’s important and very useful that the
angle range should be user defined. For instance I want to only search for vertical
lines. I would like to extend the HoughTransform2DLinesImageFilter class to
have that functionality but none of the functions are virtual. Can someone
guide me on the best way to do this? Thanks,<o:p></o:p></span></font></p>
