Feature-Oriented Image Reconstruction and Aero-Optic Metrology in Turbulence.

Abstract

Cognitech researchers have worked with Dr. Brent Ellerbroek of Philips Laboratory on the task of restoring noisy, blurry images which arise in aero-optic metrology. Cognitech's TV and MTV (recently developed by Dr. Rudin) algorithms were applied to Philips supplied data using experimentally obtained point spread functions and various nonlinear noise models. The algorithms were speeded up using an implicit method which allowed the constraints to be enforced for large time marching steps. The results, successfully applied to real images, are displayed.
