基于局部三阶差的红外小目标图像背景抑制算法

摘要

针对复杂背景下红外小目标检测中的背景抑制难题,提出一种基于局部三阶差的红外小目标图像背景抑制算法,采用局部三阶差滤波和去虚假目标来抑制背景并增强目标.仿真结果显示该算法在背景抑制、提高图像信噪比及对比度方面有着很强有效性和稳健性.%Aiming at the difficulty of infrared small target detection under complex background, an background suppressing algorithm based on local third order difference is proposed,in which local third difference filtering is applied to suppress the background and enhance the target. The simulation results show that this algorithm is very effective and robust in suppressing the background and improving the SNR and contrast.
