[ITK] [ITK-users] error using Richard-Lucy deconvolution

Hi Matt,
I don't know if you are aware that a similar problem happens when the input image does not have spacing equal to 1 mm and the direction matrix equals to identity matrix. Besides, even that you set the origin, spacing and direction of the kernel equal to the input image the same error occurs because the origin, spacing and direction of the kernel is not updated.

The implementation of this part of the filter should be equal to the other iterative deconvolution filters, like the itkLandweberDeconvolutionImageFilter.

Thanks,
Francisco

Hi Francisco,

I think you found a bug -- the kernel should not require the same Origin as the input image.  Please review this patch:

Thanks,
