Scene-based Nonuniformity Correction with Video Sequences and Registration
TL;DR: A new, to the authors' knowledge, scene-based nonuniformity correction algorithm for array detectors that relies on the ability to register a sequence of observed frames in the presence of the fixed-pattern noise caused by pixel-to-pixel non uniformity.
Journal ArticleDOI
Statistical algorithm for nonuniformity correction in focal-plane arrays.
TL;DR: A statistical algorithm has been developed to compensate for the fixed-pattern noise associated with spatial nonuniformity and temporal drift in the response of focal-plane array infrared imaging systems, and the restored images compare favorably with those restored by use of a multiple-point calibration technique.
Journal ArticleDOI
Maximum a posteriori image and seeing condition estimation from partially coherent two-dimensional light detection and ranging images
TL;DR: The use of a fast, iterative, maximum a posteriori (MAP) estimator is demonstrated and validated to estimate both the original target scene and the ensemble-averaged atmospheric optical transfer function parameterized by Fried's seeing parameter.
