<body class='hmmessage'><div dir='ltr'>Hello,<div><br></div><div>Thanks for your answer!</div><div><br></div><div>I am using unsigned short as image type both for the input and the output image. Is this the correct type for 3D CT images? Also, would you mind explaining me the way the radius for the local region is selected for 3D images? In 2D I know that a radius value of 1 corresponds to a 3x3 region, a radius of 2 is a 5x5 region and so on. Is it the same in 3D, i.e. a value of 1 is a region of 3x3x3?</div><div><br></div><div>Many thanks,</div><div><br></div><div>Mirco<br><br><div><hr id="stopSpelling">Subject: Re: [Insight-users] NoiseImageFilter for 3D images<br>From: blowekamp@mail.nih.gov<br>Date: Fri, 16 Aug 2013 08:48:56 -0400<br>CC: insight-users@itk.org<br>To: mirco9091@hotmail.it<br><br>Hello,<div><br></div><div>What are your template parameters to the filter i.e. the image types used?</div><div><br></div><div>I just tried this filter in SimpleITK with a couple different images and it seems to work fine.</div><div><br></div><div>Thanks,</div><div>Brad</div><div><br><div><div>On Aug 16, 2013, at 5:05 AM, Mirco Serra <<a href="mailto:mirco9091@hotmail.it">mirco9091@hotmail.it</a>> wrote:</div><br class="ecxApple-interchange-newline"><blockquote><div class="ecxhmmessage" style="font-size:12pt;font-family:Calibri;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;orphans:2;text-align:-webkit-auto;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;"><div dir="ltr">Hi guys,<div><br></div><div>I am trying to use the NoiseImageFilter class in order to get the local standard deviation of a 3D DICOM/nrrd dataset. The filter works nicely with 2D images, but when I try to use for 3D datasets it does not work properly and it returns an image with only zeros as intensity values. Do you have any idea why this could happen? I struggled with it a lot but I could not find a solution!
