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.
