[Insight-users] Segmentation of articular cartilage from MR images

[Tadimalla, Sirisha]

Hi all, 

I need to develop an automatic method to segment articular cartilage in 2D MR scans. I am using the following steps currently: 

Curvature anisotropic diffusion
Gradient magnitude image filter
Threshold image filter
fast marching image filter
binary morphological closing

But the output that I get is very crude segmentation. I am obtaining all other parts of the image having similar intensity ranges as cartilage like ligaments and meniscus and so on. How do I use a robust method to obtain just the cartilage?
