There is no such thing as a best way.

The isolated connected image filter is "one way to do it."

It will provide an intensity level that just separates the region
with the first seed point from the region with the second seed
point. It will also produce an output image with all the pixels
in the region set to whatever value you want.

I'm not sure what you mean here. If you are getting pixels in
your segmentation that are not part of the structure you want you
may want to try some other segmentation methods.
