Which is the best method for edge detection in this image

I have the following image but the methods that exist in MATLAB (Sobel,Canny etc) don't give something acceptable. Does anyone have an idea on what should I do? I think the problem is that there is noise outside the interface but no matter how much I tried to eliminate it either the noise remain or the method affects the interface. The image is obtained with a correct procedure and what I'm asking is what I can furtherly do.
Thank you very much in advance

You can run a gaussian kernel first on the image followed by canny edge detector to see if that achieves good results
