[Community] [Insight-users] Line SpatialObjects returned from Hough Transform

[Richard Frank]

Hi,

I don't seem to understand how lines are returned from the HoughTransform2dFilter.

I have a preprocessed binary tiff file the contains some thin white rectangles. In Matlab, I can easy find using Hough  and draw the lines on top of the image, so the input data is fine. 

In ITK I write out the Hough space and see peaks where they probably should be.

But the line output doesn't make sense to me. Looking at the code, it seems it's perhaps storing p and theta in the line spatial object?

I ran the example and the output from my inputs are not my lines....

Thanks

Rick
