Adaptive offset updating infrared image scene correction method

The invention relates to an adaptive offset updating infrared image scene correction method, and belongs to the technical field of infrared image processing. According to the method, an infrared 14-bit original image frame sequence is used, pixel-level motion estimation is carried out on the image frame sequence, offset correction matrix updating is carried out on image frames judged to be in motion, and the offset correction matrix is used for correcting the image frame sequence so as to reduce the non-uniformity of the image. According to the method, image details can be better reserved while image heterogeneity is removed, image ghosting cannot be introduced, the algorithm complexity is low, and embedded implementation can be achieved. 本发明涉及一种自适应偏置更新红外图像场景校正方法，属于红外图像处理技术领域。本发明使用红外14位原始图像帧序列，对图像帧序列进行像素级运动估计，对判定为运动的图像帧进行偏置校正矩阵更新，使用偏置校正矩阵对图像帧序列进行校正，以降低图像的非均匀性。本发明在去除图像非均匀性同时，能更好的保留图像细节，不会引入图像鬼影，算法复杂度低，可嵌入式实现。
