Nonuniformity is a key factor that influences the performance of the infrared focal plane arrays (IRFPA) imaging system. A nonuniformity correction algorithm based on discrete sequence wavelet transform for IRFPA is presented. The infrared image sequences of detectors are decomposed by the discrete sequence wavelet transform. And then correction coefficients of the offset and the gain for NUC are...
A scene-based nonuniformity correction (NUC) algorithm for infrared focal plane arrays (IRFPA) is presented. In this algorithm, the infrared image sequence is decomposed by utilizing the discrete sequence wavelet transform. The corresponding statistics are calculated, and then the offset and the gain coefficients for IRFPA NUC are achieved ultimately. The algorithm achieves good NUC capability, which...
