Hello Rong,<div><br></div><div>the documentation of <a href="http://www.itk.org/Doxygen/html/classitk_1_1CannyEdgeDetectionImageFilter.html#details">http://www.itk.org/Doxygen/html/classitk_1_1CannyEdgeDetectionImageFilter.html#details</a> states that the input image can have arbitrary dimensions. So, you should be able to use canny edge detector on 3D images. Follow this example <a href="http://www.vtk.org/Wiki/ITK/Examples/Broken/EdgesAndGradients/CannyEdgeDetectionImageFilter">http://www.vtk.org/Wiki/ITK/Examples/Broken/EdgesAndGradients/CannyEdgeDetectionImageFilter</a> but be aware that this is also a 2D example. Your code should be the same except for the image template definition step where you should use the proper image template (3 Dimensions)</div>

Hi, <br><br>I am a new man in using ITK library, and I want to realize a edge detection in 3D ultrasound data. However, I read ITK software guide 2.4, and found it seemed canny edge detection or canny-edge level set segmentation just can used for 2D images. So I am not sure are there any edge detection methods I can use for 3D data? Could you please give me some advice ?<br>
<br>I will appreciate your help! Thank you!<br clear="all"><br>-- <br><br> ---------------------<br>Best Regards!<br><br>===============================================<br>Rong Xu, Ph.D Student<br>Ohya Lab<br>Graduate School of Global Information
