LensDistortionCorrection

LensDistortionCorrection[image,{tx,ty},theta,{p1,p1},{k1,k2,k3...}] performs a lens distortion correction along with a generalized translation (t) and rotation (theta). p1 and p2 specify 1st order astygmatism and k1-6 the different orders of distortion beyond that. Note you only need to supply k's up to the desired order of correction.

It's chaos...be kind.
