[Insight-users] the overflow of itk::AddImageFilter

[dominique at toepfer-web.de]

Hi,

would float as output type really give you a "cut-off" at 255? I don't know if there is a filter for that, but you could use image iterators and take care of the correct values yourself.

Set the output image to that of floating point pixels. That should get you the correct values.

hello everyone,
i got a problem when using AddImageFilter.I want to keep the pixel-wise=255 (for my 8-bits scale images),when the overflow happens ,but  the AddImageFilter's has such a description  
 Warning:    No numeric overflow checking is performed in this filter. 
i add the segmented contour image(pixels on the contour = 255) and the original image.while i use the AddImageFilter,the overflow happens and i cannot get a meaningful outcome.  
how can i manage it,does any member function of this class provide any method that is responble to the overflow?
thanks in advance.
Quan
