[Insight-users] Concept for edting segmented mask images

[Dawood Masslawi]

Hi Xiaopeng,
You can use one of the available edge detection filters in the ITK to extract the boundary 
contours. Changing the shape of the contours could be a little bit more tricky, my
suggestion is to adapt one of the transformation functions in the ITK based on the kind of
change you want to induce in the contours (e.g. scaling, shearing, inflation and etc.). 
Of course there are numerous other ways as well, but ultimately the best option depends
on the kind of change you want to make.
After resampling you should have no problems generating the mask images.
Best regards,
Dawood

Dear Users,

 

I utilized itk segmentation algorithm to extract the liver from CT images.
The results are a series of binary images (mask images). For editing the
binary images, for example deleting some part, I have an idea as follows.

 

First, generating boundary contours from binary images.

Second, changing the shape of the contours.

Finally, generating mask images from the edited contours.

 

Could you tell me whether this idea is feasible or not? If not, please give
me better ideas.

 

Thanks,

Yang
