Robust Approach for Nonuniformity Correction in Infrared Focal Plane Array
In this paper, we propose a new scene-based nonuniformity correction technique for infrared focal plane arrays. Our work is based on the use of two well-known scene-based methods, namely, adaptive and interframe registration-based exploiting pure translation motion model between frames. The two approaches have their benefits and drawbacks, which make them extremely effective in certain conditio...
متن کاملFast Adaptive Nonuniformity Correction for Infrared Focal-Plane Array Detectors
A novel adaptive scene-based nonuniformity correction technique is presented. The technique simultaneously estimates detector parameters and performs the nonuniformity correction based on the retina-like neural network approach. The proposed method includes the use of an adaptive learning rate rule in the gain and offset parameter estimation process. This learning rate rule, together with a red...
متن کاملDerivative Based Focal Plane Array Nonuniformity Correction
This paper presents a fast and robust method for fixed pattern noise nonuniformity correction of infrared focal plane arrays. The proposed method requires neither shutter nor elaborate calibrations and therefore enables a real time correction with no interruptions. Based on derivative estimation of the fixed pattern noise from pixel sized translations of the focal plane array, the proposed meth...
متن کاملAn algebraic algorithm for nonuniformity correction in focal-plane arrays.
A scene-based algorithm is developed to compensate for bias nonuniformity in focal-plane arrays. Nonuniformity can be extremely problematic, especially for mid- to far-infrared imaging systems. The technique is based on use of estimates of interframe subpixel shifts in an image sequence, in conjunction with a linear-interpolation model for the motion, to extract information on the bias nonunifo...
متن کاملAdaptive Nonuniformity Correction in Focal Plane Array Sensors for Infrared Imaging
This report presents both calibration-based (two-point calibration) and scene-based (Kalman filtering and multiple-model adaptive Kalman filtering) techniques and their performances for nonuniformity correction (NUC) in infrared focal-plane-array sensors assuming both linear and S-shape detector response models. Two-point calibration performs radiometrically accurate NUC; however, it increases ...
