Hi All:<br><br><div id="result_box" dir="ltr">I currently use 'Geodesic Active Contour Level Set Mehtod' for image segmentation.<br>My input is a DICOM 3D image and its type is signed short.<br>Because the demand for level set, this image must be casted to float.
<br>However, after the execution of GradientMagnitudeRecursiveGaussianImageFilter,<br>the output image is black.<br>After I checked in the entire process, I guess the reason is data type error.<br>What means can be taken to resolve the matter?
<br><br>Regards.<br> </div>
