[Insight-users] Problem with Canny Edge Detection

[Luis Ibanez]

Hi BeeJay,

You are instantiating this filter for images
of pixeltype 'char', but it expects a pixel
type 'float'.

Please convert the pixel type.

You may use the CastImageFilter for converting
the input image from pixel type 'char' to
pixel type 'float'


Regards,


     Luis
