摘　　要：红外图像的非均匀校正是红外成像领域研究的核心和热点问题,本文针对小波变换和传统中值滤波校正的不足,提出了一种改进中值滤波结合小波变换的非均匀校正算法,实验仿真表明该方法优于单纯小波校正和传统的中值滤波校正.The non-uniformity correction of infrared images is a core and hot issue in the research area of infrared imaging.In this paper,according to the disadvantage of wavelet transform and traditional median filter,we proposed a non-uniformity correction algorithm based on improved median filter and wavelet transform.Through extensive simulation,we showed that our method was better than traditional wavelet correction and median filter correction.
