2011/6/20
针对卡尔曼跟踪算法在非线性非高斯情况下跟踪结果不再准确,以及粒子滤波跟踪算法计算量大难以满足实时性的缺陷,提出了卡尔曼滤波及粒子滤波相结合的算法。利用卡尔曼滤波进行跟踪得到候选目标并计算目标模型与候选模型的匹配程度,若与目标模型匹配度小于一定阈值,则转换跟踪方式利用粒子滤波进行跟踪来修正卡尔曼滤波结果;同时,采用"模板缓冲区法"对目标模型进行更新以保证跟踪的连续性、稳定性及准确性。实验结果表明,这...
针对超分辨率图像重建中图像运动估计精度要求高,速度要求快的问题,对传统的基于Fourier-Mellin变换和Keren算法的运动估计方法做出以下改进:首先提取参考图像和待估计图像的边缘,从而避免了Fourier-Mellin变换的不足(对细节不明显的图像运动估计精度极差);由于只是用Fourier-Mellin变换进行粗估计,对角度估计精度要求不高,只需小于1°,因此在进行对数极坐标变换时,可以...
