一种红外图像横纹去除方法
By using an intra-frame statistical correction method, the brightness of odd-numbered rows is dynamically compensated to eliminate horizontal stripes in infrared images, solving the image quality problem caused by differences in readout circuits and achieving real-time and efficient correction in dynamic scenes.

Abstract
本发明属于图像处理技术领域，具体涉及一种红外图像横纹去除方法。本发明方法采用一种基于帧内统计的校正方法，以偶数行作为亮度基准，针对奇数行进行校正，通过计算奇数行与偶数行的灰度值差异，对奇数行进行相应的补偿，使得奇数行的亮度与偶数行保持一致，从而消除奇偶行读出电路之间差异导致的横纹现象；本发明方法采用垂直方向列均值数组对局部差值图像进行调整，避免了图像被补偿后目标边缘出现的锯齿错位问题，保证去除横纹的同时不影响图像质量；本发明方法针对每一帧图像单独补偿，适应动态场景，同时计算量小，适合实时处理。
