<br>Hi Markus,<br><br>ITK assumes that images to be Added must have the same dimensions<br>and number of pixels along every dimension.<br><br>You should crop the larger image to the size of the smaller image,<br>using the RegionOfInterestImageFilter.
<br><br> OR<br><br>You could extend the smaller image to the size of the larger image<br>by using the PasteImageFilter, or by using a ResampleImageFilter<br>with an IdentiyTransform.<br><br><br> Regards,<br><br><br>

<br>WeightedAddImageFilter is the Problem.<br>I have two images. One with a dimension of 640x512 and the other one is<br>arbitrary but let it be 280x252 and starts relative to the bigger one at<br>180x140. Now I want to add the smaller one to the bigger one starting at
<br>the position of which the smaller one is translated.<br>I tried nerly everything to do that but I allways got an invalid pointer<br>from the pixelaccessor. Input 1 is the bigger image and Input 2 the<br>smaller one. I set the requested region of the bigger one to the
<br>coordinates of the smaller one but it does not work. Setting no<br>requested region also. I turned on and off SetInplace but still the same<br>problem. Is it possible to add a smaller image to a bigger one?<br><br>Thank you for your help.
