Hi Sara,<div><br></div><div>I don't know whether this is the same or different problem, but when I tried to do something with similarly large image (512x512x497), using double precision internally (nearly 2GB), it constantly failed to allocate on 32-bit system, even though I had enough free memory. After spending some time trying to figure out what was going on, I concluded that the image fails to allocate because my memory space was fragmented - even though there was enough free memory overall, there was no free block large enough into which my image would fit. This problem is resolved by switching to 64bit OS+app.<div>

I then replaced the RecursiveGaussianImageFilter with the GradientMagnitudeImageFilter since it requires less memory. These fixes did not solve my problem. I next commented out one filter at a time and found that I get the memory error when I include the ImageFileReader, CastImageFilter, and GradientMagnitudeImageFilter. </div>
<div><br></div><div>Could you suggest any further fixes? I am working on a Mac with 2G of memory. The image I'm working with is 402 MB (1024x1024x402).</div></div><br>_____________________________________<br>
