Fit
From Sample Arrays to Curves

Abstract: Fit generates a set of synthetic curves given a sampled image. It does this in two steps. First, it uses an edge-finder to produce a set of fine-grained polygons (also known as sample sequences or contours). Then, it uses PiecewiseFit to find a compact set of piecewise parametric cubic curves that approximate the samples.

1. Finding Samples
Outline and Centerline
Outline.mesa finds edges at intensity transitions. It finds boundaries of regions. Coastlines come to mind.
Centerline.mesa asumes that you are fitting a line-drawing and tries to lay down edges down the centers of things.
2. Fitting the Samples
