During digital video acquisition, imagery may be degraded by a number of phenomena including undersampling, blur, and noise. Many systems, particularly those containing infrared focal plane array (FPA) sensors, are also subject to detector nonuniform

The design of imaging systems involves navigating a complex trade space. As a result, many imaging systems employ focal plane arrays with a detector pitch that is insufficient to meet the Nyquist sampling criterion under diffraction-limited imaging c

We present a numerical wave propagation method for simulating imaging of an extended scene under anisoplanatic conditions. While isoplanatic simulation is relatively common, few tools are specifically designed for simulating the imaging of extended s

An extension of the fusion of interpolated frames superresolution (FIF SR) method to perform SR in the presence of atmospheric optical turbulence is presented. The goal of such processing is to improve the performance of imaging systems impacted by t

In many undersampled imaging systems, spatial integration from the individual detector elements is the dominant component of the system point spread function (PSF). Conventional focal plane arrays (FPAs) utilize square detector elements with a nearly

Imagery acquired with modern imaging systems is susceptible to a variety of degradations, including blur from the point spread function (PSF) of the imaging system, aliasing from undersampling, blur and warping from atmospheric turbulence, and noise.

The presence of parasitic jitter in video sequences can degrade imaging system performance. Image stabilization systems correct for this jitter by estimating motion and then compensating for undesirable movements. These systems often require tradeoff

Common infrared video imagery can experience large variations in signal level across different portions of a scene. Global image processing techniques are not capable of using standard displays to show both large variations and detail within individu
