摘　　要：文中提出了一种基于相似度的粗精双搜索运动多目标识别方法。在粗搜索阶段,基于距离相似度准则,根据位置特征,预测下一时刻目标可能出现的区域;在精搜索阶段,基于几何相似度准则,根据形状特征,找出粗搜索区域内形变最小的目标跟踪。实验结果表明该方法可快速、准确地从多目标中识别出待跟踪的目标,并对其进行稳定跟踪。This paper presents a moving multi-target recognition method based on conformability degree in the cursory searching process and the precision searching process.In the cursory searching process,based on the distance conform- ability degree principlc,according to the position characteristic,predict the area where the target may appear in the next moment.In the precision searching process,based on the geometry conformability degree principle,according to the shape characteristic,find out the target of minimum deformation in the area of the cursory searching.The experimental result shows that this method can distinguish the target to be tracked from many targets quickly and correctly,and track it steadily.

关 键 词：多目标识别 电视跟踪 距离相似度 几何相似度 代价函数
