Ash, I don't know if marwa ever did. However, if you're interested in a thresholding method (which marwa is NOT ) then you can see my attached demo.

You can use manual tracing. See attach demos for imfreehand().

Then look at deep learning. It's the only other way I know of without thresholding in it explicitly. However you know that deep learning has thresholding internal to the algorithm, though it's hidden from you.
Why do you need a way without thresholding?

Yes, though you could come up with an automatic threshold selection algorithm that could perhaps pick what you'd pick yourself.
See my interactive, visual thresholding application: https://www.mathworks.com/matlabcentral/fileexchange/29372-thresholding-an-image

please can you help me in this task : how to segment brain lesions using intra class variation and morphological operation as in this figure and thanks in advance

Sorry, no.
Perhaps I can help if you give something much, much smaller to ask about rather than programming up a whole algorithm, which could take hours to months to do.

Lots of preexisting packages out there that are free for acadmic use:
SPM (which runs on matlab)
FSL (compiled c++ runs on LINUX and MAC OS X)
ANTs (runs on LINUX and MAC OS X)
Googling will get you the links.
