	Detecting of multi-target in sea or sky background based on wavelet energy (EI CONFERENCE) 会议论文 OAI收割 Advanced Sensor Systems and Applications II, November 8, 2004 - November 12, 2004, Beijing, China 作者: Liu G. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 The technology of multi-target tracking is always detecting small targets in complex background. According to the frequency characteristic of nature background and small target a method of detecting targets based on wavelet energy is suggested. The energy of targets in horizontal and vertical direction outclass that of background or we can say the gray degree of targets outclass that of background. Then through selecting adaptive region-value targets and background can be divided. By the method of classifying the figure centers of every target can be calculated. According to the figure centers of every target in several neighboring frames the position and velocity of every target in next frame can be estimated by Kalman filter. Experiment results have shown that small targets in sea or sky nature background can be detected by this method and they can be tracking.
