Segmenting the nerve like structures in a low resolution image

I have an image like the one attached,
It has low quality and the edges are not very clear. Any idea how to segment the nerve-like structures? I've tried the coherence filter, Frangi filter, and Gabor filter and still, I don't have a satisfying result.
Any help is appreciated.

Well you could try anisotropic diffusion (demo attached) or a tophat filter or a Kuwahara filter (demo attached), though I don't hold out great hope for those either. But they're worth a try.
Then there are more sophisticated noise reduction routines like BM3D, non-local means, non-local means 2, UINTA, K-LLD, K-SVD, etc. See the bible of image denoising overviews: https://users.soe.ucsc.edu/~milanfar/publications/journal/ModernTour.pdf by one of the leaders in the field.

I suggest you look at the papers, or hire someone to develop an algorithm for you. This is not simple and would take way too much time - way more than I can donate to you. Plus, it seems like there are judgment calls involved as to whether a little, disconnected bright blob should be considered as part of a nearby nerve trace or not. Good luck though.
