Abstract

According to the imaging mechanism of the IR image, the histogram of the IR image, whose background is composed of the sea area and the sky area, usually has two apices and one vale. Based on this character of the histogram, the paper proposes a background suppression method, which combines the sea-sky area segmentation with the median filtering. Then, in order to reduce random noises in the image whose background has been suppressed, the local threshold-a digitizing method-has been showed in the paper. In this method, the image whose background has been suppressed is divided into some blocks, and the different block has the different threshold. The target motion is continuous and the noise motion is random, so the paper presents a sequential target detection method on the centroid track accumulation. A large number of experiments show that the methods presented in the paper can exactly detect the moving small target in the IR clutter background containing sea and sky areas.
