I've been out of the Machine Vision space for a while, so my knowledge is somewhat out of date.

What research is out there on general Affine invariant vision algorithms and techniques?

For context, my practical experience ended in the mid 2000's when "jittering" was a bit of thing along with some occasional closed form estimators based on basic linearization approximations.

ASIFT or Affine SIFT is one of the Affine invariant versions of SIFT. Take a look here - http://www.cmap.polytechnique.fr/~yu/research/ASIFT/demo.htm....

It's actually perspective transform invariant, which is a more general class. The name is misleading.

SIFT and its multiple descendants, yes, and also things like Random Ferns, google "Boosted Random Ferns for Object Detection" (it's damn difficult to get a clean link to pdf from google...)
