A water surface small target detection approach inspired by dragonfly vision mechanism

摘要

Weak and small target detection technique is widely used in military and industry applications. The targets are weak and small in the image when targets are far from the imaging system. Under this complex condition, the image has very low SNR and it is difficult to detect the targets. On this situation, a weak and small target detection approach based on dragonfly compound eye is proposed in this paper. Dragonfly compound eye has obvious characteristics of polarized light, and it can detect the surface of water and the targets on water accurately. The new method uses the polarization characteristics of dragonfly compound eye to get the polarization image of targets, and then completes the weak small target detection. The experimental data shows that this new target detection method has advantages of high precision and small false alarm rate.
