[Insight-users] itkHoughTransform2DLinesImageFilte

[Andinet Enquobahrie]

Hello Frank,

Thank you for reporting the bug. GetLines() method in the 
"HoughTransform2DLinesImageFilter" assumes the output image pixel type 
to be ALWAYS of type float which is a bug. In addition, in GetLines() 
method, an output image is defined and its memory allocated 
unncessarily.   GenerateData() method takes care of that. I have made 
the changes and committed a fix to cvs. Please, update your version and 
give it a try. Let us know if it solves your problem...
