Paper Abstract

Sensor jitter introduces non-white noise fluctuations in imagery of cluttered scenes. These fluctuations are a major source of interference in the detection of weak time-dependent signals, which may be associated with a subject's appearance, motion, or brightness modulation. Due to the presence of sensor pattern noise and uncertainty in the scene's subpixel spatial structure, standard frame-to-frame registration methods have limited ability to model and remove these fluctuations. A simple temporal whitening approach, applicable to a wide variety of imaging systems, is found to be highly effective for suppressing subpixel jitter effects, leading to dramatic (up to several orders of magnitude) improvement in signal detection ability.
