提出了一种基于边界灰度投影匹配的全局运动估计和运动目标提取算法.算法将边界灰度水平投影和垂直投影值作为匹配特征,较好地估计了全局运动参数.由于只需计算一维特征向量所以降低了全局运动估计的计算量.经过全局运动补偿后,可以运用传统的帧间差法得到运动目标.为了减少噪声的影响,准确地提取到目标,采用了高阶统计量的方法(HOS)来区分背景和运动目标.试验结果证明所提出的方法在估计全局运动参数和提取运动目标方

针对弱小目标对比度较低、边缘模糊、难以准确探测的问题,本文提出一种基于PDE的改进的各向异性扩散滤波算法增强弱小目标。该方法根据各向异性扩散原理,通过改进传统的P-M方程建立新的滤波模型,采用自适应滤波的方法在非目标区进行背景平滑,在局部变化的区域进行锐化处理增强弱小目标,从而达到背景平滑的同时增强边缘的效果。同时可以通过调节参数k和w选择平滑和锐化的程度,以适应不同的环境变化。实验结果表明,该方
