Hey yall, I am trying to smooth this data on a surf plot so this forms more of a curve while also putting a curve line line over it. How would I go about doing that? Thank you so much!

If you were to find() the locations of the non-zero pixels, then you could use boundary() on the coordinate pairs to get an outline of the area. With that information in place, you might consider something like John's interparc() from the FIle Exchange.

Thank you! Although I am still a little confused on what I would then do with the interparc data(It is currently a 100x2 double matrix). Would I go about turning these points back into matrix form?
