[Insight-users] Question about CannyEdgeDetectionImageFilter

[Zachary Pincus]

In English, then my very poor translation to Spanish:
En Ingles, entonces un pobre traducción a Castellano:

(1) The CannyEdgeDetectionImageFilter class uses parameters with the  
same name as those in the filters you mention below, but they have  
different meanings for the Canny filter. I suggest that you read more  
on the Canny filter and what its parameters are. This information is  
readily available on the internet.
(2-4) The Canny filter requires no previous steps: it can be applied  
to raw images, and produces immediately usable output.

(1) El clase CannyEdgeDetectionImageFilter usa parámetros con nombres  
eguales a los del filtros cuales menciona Ud. abajo, pero tienen  
sentidos differentes para el filtro Canny. Propongo que leé Ud. en el  
filtro Canny y sus parámetros. Esta información es disponible por el  
Internet.
(2-4) El filtro Canny no necesita algunos acciones anteriores: se  
puede aplicar a imagenes crudos, y produce resultados utilizable  
directamente.
