<div>Hello, dear all.</div>
<div> </div>
<div>I am trying to use GradientRecursiveGaussianImageFilter, but there is exception while running. I am thinking may be it is out of memory since the size of the image is 512*512*272. I am wondering is there any other filters that I could use instead of this one. Actually, I just want to use the gradient vector of a few points. Is there a better way to calculate the gradient vector. Thanks a lot.</div>
