Abstract: In order to realize infrared image adaptive correction, a method to adaptive correct the non-uniformity(NU) based on wavelet transform histogram normalization was introduced. The new algorithm used the orthogonal wavelet transform to analyze image, calculated the decomposition image histogram of the neighborhood elements of a single pixel, got median histogram by sorting pixels neighborhood histogram and completed decomposition image non-uniformity correction using the mean histogram normalization. Finally, a final result in all scales after the correction by using the inverse wavelet transform was obtained. According to the practical application, this algorithm has the advantage of fast convergence speed and high precision.
