Dimensional reduction methods have significantly improved the simplification of Pulsed
Thermography (PT) data while improving the accuracy of the results. Such approaches …

Fixed-pattern noise (FPN), which is caused by the nonuniform opto-electronic responses of
microbolometer focal-plane-array (FPA) optoelectronics, imposes a challenging problem in …

Following calibration, hyperspectral images remain affected by spatial dimension
nonuniformity, ie, stripe noise, due to stray light interference, slit contamination, and …

A generalization of a recently developed algebraic scene-based nonuniformity correction
algorithm for focal plane array (FPA) sensors is presented. The new technique uses pairs of …

Flat-field correction (FFC) is commonly used in image signal processing (ISP) to improve the
uniformity of image sensor pixels. Image sensor nonuniformity and lens system …

Non-uniformity is a common phenomenon in infrared imaging system, which seriously
affects imaging quality. In view of the problems of existing non-uniformity correction of …

In this paper, we present a new adaptive image registration nonuniformity correction method
with the function of eliminating ghost artifacts. This method assumes that the irradiation of …

Thermal array detectors, also known as focal-plane arrays (FPA), are a rapidly develo**
technology and are used in a variety of civil, medical and military applications. The …

We present an adaptive technique for the estimation of nonuniformity parameters of infrared
focal-plane arrays that is robust with respect to changes and uncertainties in scene and …

Nonuniform exposures often affect imaging systems, eg, owing to vignetting. Moreover, the
sensor's radiometric response may be nonlinear. These characteristics hinder photometric …
