After giving a seminar at the Cavendish lab in Cambridge UK by videocon, I spent most of my research day talking with Fergus, discussing his model of residual speckle patterns in coronograph images from Oppenheimer's group. Fergus's model is extremely general, but has strong priors which "regularize" the solution when there isn't much data or the data aren't troublesome. Because it is so general, the model is in fact very simple to write down, has analytic derivatives, and can be optimized quickly by some (pretty clever) Matlab code. We decided that he should run on everything and then we should meet with Oppenheimer's group to decide what's next. I think we might be able to improve the sensitivity of coronographs generally with these models.
