Indeed, there are several methods to clip the foreground; some faster than others, depending on the image.

But my problem is mainly, in fact, the blurring of the background.
With "Gaussian blur", there is the problem of the halo; it is avoided with "median blur"; but I find the result less natural. 
Maybe I'm too demanding...

Did you try the Lens blur with a focus map?
