New temporal high-pass filter nonuniformity correction based on bilateral filter
TLDR
A new scene-based NUC technique based on bilateral filter has been developed that separates the original input frames into two parts and it estimates the NUC parameters only by using the residuals.Abstract:
A thorough analysis of low convergence speed and ghosting artifacts in temporal high-pass filter correction has been undertaken in this paper and it has found out that the keys of these problems are the interference of a large sum of unrelated scene information in the nonuniformity correction (NUC) process. In order to overcome these drawbacks, a new scene-based NUC technique based on bilateral filter has been developed. This method separates the original input frames into two parts and it estimates the NUC parameters only by using the residuals. The experimental results have shown that it can significantly increase convergence speed and reduce ghosting artifacts.read more

Scene-based nonuniformity correction algorithm based on interframe registration.
TL;DR: A simple and effective scene-based nonuniformity correction (NUC) method for infrared focal plane arrays based on interframe registration that estimates the global translation between two adjacent frames and minimizes the mean square error between the two properly registered images.

ADMIRE: a locally adaptive single-image, non-uniformity correction and denoising algorithm: application to uncooled IR camera
Yohann Tendero,Jérôme Gilles +1 more
TL;DR: The proposed method uses an hybrid scheme including an automatic locally-adaptive contrast adjustment and a state-of-the-art image denoising method that permits to correct for a fully non-linear NU and the noise efficiently using only one image.

TL;DR: The experiment results indicate that the proposed algorithm can not only reduce the non-uniformity with less ghosting artifacts but also overcome the problems of image blurring in static areas.

Scene-based nonuniformity correction method using multiscale constant statistics
TL;DR: A new statistical NUC method called the multiscale constant statistics (MSCS), which statically considers that the spatial scale of the temporal constant distribution expands over time and introduces an exponential window and a tolerance interval for the acquired data to capture the drift in nonuniformity and eliminate the ghosting artifacts.

Improved interframe registration based nonuniformity correction for focal plane arrays
TL;DR: An improved interframe registration based nonuniformity correction algorithm for focal plane arrays using an outliers exclusion scheme and a variable step size strategy to promote the correction precision considerably, but also eliminate ghosting artifacts effectively is proposed.

Nonuniformity two-point linear correction errors in infrared focal plane arrays
TL;DR: In this paper, the error and residual nonuniformity in an IR focal plane array, after two-point linear non-iformity correction, which results from measurement errors and nonlinearity, is calculated, yielding different results than have been obtained in the past.
