Paper Abstract

Daubechies wavelets are applied to the fixed pattern noise measured by a 336-by-165 Honeywell uncooled microbolometer infrared sensor and by an Amber AE 4128 128-by-128 indium antimonide (InSb) staring array. The main hypothesis presented in this paper is that Daubechies wavelets are the proper filter for the noise, because they decorrelate the temporal pixel responses on both arrays. These results are an experimental verification of the basic wavelet research of Flandrin with significant additions by Tewfik and Kim.
