Hi everybody  
I want to develop a method to detect shapes in the images(for example blobs).  
I’ve found Hough-Transform to reach this goal, but I can’t find it in SimpleItk.  
Does SimpleItk support Hough-Transform?  
If it doesn’t, how can I detect shapes in SimpleItk?  
I’ll be so grateful if you help me.

Hello @Mahdiye_Imanpanah,

The ITK [HoughTransform2DCirclesImageFilter](https://itk.org/Doxygen/html/classitk_1_1HoughTransform2DCirclesImageFilter.html) is currently not included in SimpleITK.

To request that it be added to SimpleITK, please create a feature request on the [toolkit’s issue tracker](https://github.com/SimpleITK/SimpleITK/issues).
