A new spatial and temporal infrared small target detection method

Abstract

To detect dim small target in infrared images, considering the target velocity and intensity characteristics we proposed a new spatial and temporal method. The new spatial and temporal method consists of a 2D spatial model and a 3D spatial and temporal model. The 2D spatial model is utilized to pre-process of the original infrared images. The 3D spatial and temporal model is used to enhance the probable targets by estimating the direction of the target and accumulating the grayscale to the central pixel. Experiments show that our method gains better detection performance in infrared videos with the complex background.
