The code to generate this cartoon is in my answer to the XKCD-ification question. When executed in Mathematica, there is even a secret mouse-over message.

You have extra { } in the input data. You can remove them by AutocorrelationTest[Flatten[data],1]

comment Segmentation of a microscopy image with uneven illumination
Your question was about cleaning up the background. Try different binarization values, or try using the above binarization as a mask (to multiply by the original).

comment How do I find the expression for where the first derivative equals 0?
The color (blue) of the function was Mathematica's way of telling you that the function was undefined.

If you really want to square it (rather than take the square root) then change the line to dt = Sqrt[(p2tx - p1tx)^2 + (p2ty - p1ty)^2]

If you change the two copies of Sqr to Sqrt then Solve does give an answer.
