[Insight-users] about initial level set

[Yixun Liu]

Hi,

I did as you said. However, the result is wrong.

I use the ShapeDetectionLevelSetImageFilter. It's first input is the segmented binary image and it's second input is a feature image,which  is the output of the sigmoid filter. The result is obvious wrong.  I look for the document about this filter. It says that the first input should be a initial level set, which is different from a binary image. So, in my opinion, some filters should be used to convert the bianry image to a distance map.

Best regards,

Yixun Liu
