Detecting infrared target with receptive field and lateral inhibition of HVS

Abstract

In this paper, we proposed an infrared (IR) target detection method based on the receptive field (RF) and lateral inhibition (LI). In this method, the direction parameters of Gabor filter is adaptively determined according to the gradient direction. And a background prediction method based on LI is used for regulating the gray value in image so as to achieve background suppression and target enhancement. Experimental results indicate that the proposed method can extract both small and area target from complex background, and the target detection ability is satisfactory.
