In this paper  in view of the low-flying target near the sea is always above the sea-level line  we can first locate the sea-level line  and neglect the image data beneath the sea-level line. Thus the noise under the sea-level line can be suppressed  and the executive time of target segmentation is also much reduced. A new method is proposed  which first uses neighborhood averaging method to suppress background and enhance targets so as to increase SNR  and then uses the multi-point multi-layer vertical Sobel operator combined with linear least squares fitting to locate the sea-level line  lastly uses the centroid tracking algorithm to detect and track the target. In the experiment  high frame rate and high-resolution digital CCD camera and high performance DSP are applied. Experimental results show that this method can efficiently locate the sea-level line on various conditions of lower contrast  and eliminate the negative impact of the clutter caused by waves and clouds  and capture and track target real-timely and accurately.   A method for automatic infrared point target detection in a sea background based on morphology and wavelet transform 会议论文  OAI收割 3rd International Symposium on Multispectral Image Processing and Pattern Recognition, BEIJING, China, October 20-22, 2003 作者:  Wen PZ(温佩芝);  Shi ZL(史泽林);  Yu HB(于海斌);  Wu XJ(吴晓军) 收藏  |  浏览/下载：12/0  |  提交时间：2012/06/06 infrared point-target  wavelet transform  morphology  target detection and segmentation  sea background
