I have an array which I'm attempting to filter with a Gaussian blur to smooth the surface and contour plots. Without any filtering, this is the resulting contour plot:
Gives the following contour plot:
As you can see, the contours are nicely smoothed, but the filter has blurred the transitions too much and shifted them wider and outwards.
Is it possible to refer to just array elements above a certain value for the filtering?
I'm sure it must be and I'm just being stupid not figuring it out.
