		design criteria for curve organization

1.  should  operate in presence  of large noise and  heavily textured
regions  (should  be able  to  find outlines  in  non-textured areas,
without blowing up).  The paradigm: random points are 50 times points
lying on curves.  Pairs with a noise point are 2500 times as frequent
as pairs of curve points. 
2.  should span gaps locally
3.  sensible combinatorially in view of 1 and 2
4.  should be optimal with respect to contrast sensitivity.





1. linearize around the current fit in a worm-type curve fitting
2. how much better do we do by squeezing as far as possible
on global guesses for curves
3. consequence: relation between density of curve points and length
for constant detectability
