<div dir="ltr">Hi,<div><br></div><div style>If I have an image and I would like to extract a volumetric spherical region are there filters available in itk for this. One method I was thinking was using the pastImageFilter, but this requires one to set the region which from my limited understanding doesn't allow for non square / rectangle definitions (in 2d)</div>
<div style><br></div><div style>Can anyone suggest a method or filter to use to extract e.g an ellipse / circle from an image and setting everything outside to zero?</div><div style><br></div><div style>Kind regards</div>
