<div dir="ltr"><div><div><div><div><div>Hi,<br></div>segmentation is highly dependent on the structure/tissue of interest and the modality you are using.<br><br></div>As for the pixel type that best fits your image, (signed) short is a common choice for CT images. As for the seed point, make sure you take into account the ITK's axis/orientation conventions, as well as the ones your viewer may be using. You may find it useful displaying your seed point so that you can see that you are actually placing it where you want/expect it to be.<br>

I am working for DICOM 3D segmentation.<br>
I met some problems like reader type (unsigned char or float) and how to<br>
choose seed point and so on.<br>
I tried many times but still no result. Who can help put on one example code<br>
and CT DICOM slices.<br>
<br>
I appreciate it a lot for any tips.<br>
<br>
Thanks a lot.<br>
<br>
