As I'm beginner in image processing, I am having difficulty in segmenting all the parts in DICOM image.

Currently, I'm applying watershed algorithm, but it segments only that part that has tumour.

I have to segment all parts in the image. Which algorithm will be helpful to perform this task?

The image below contains the tumour.

This image is the actual DICOM image

I looked at some picture from DICOM, and it seems that these images usually don't have many local minima, so I guess that's why watershed isn't optimal. However, it seems that in DICOM the color gradients are often strong, so I suggest to use techniques that works well with gradients:

  • Direct Gradient computations, either convolutional gradients or morphological gradients (selects shape of your different objects)

  • Normalized Cut on Similarity Graphs

If you want to know more about these you can read this post.
