Abstract
Distortion correction in an imaging system using parametric motion estimation. Parametric motion estimation is used to correct for geometric lens distortion and illumination changes. Models for geometric lens distortion and different illumination models are presented, as is a method for an iterative linearising method of solving the resulting sets of nonlinear equations.
