| 摘 要： | 针对Mean shift算法中仅使用灰度特征难于实现对红外序列图像目标准确跟踪的问题,提出了利用边缘-灰度特征相融合的目标跟踪算法.为了实现红外序列图像中目标的高效跟踪,在研究Mean shift灰度特征的基础上,根据红外序列图像的边缘方向信息与灰度信息构建了边缘-灰度目标模型,将此模型应用到目标跟踪算法中,提高了Mean shift算法在红外序列图像目标跟踪过程中的运算能力.实验证明,该方法能够增加灰度直方图对目标模型的描述能力,提高了目标跟踪算法的鲁棒性.

| Abstract: | In order to trace target in infrared sequence images efficiently,a target tracing algorithm is proposedby edge-gray features fusion and the edge-gray target model is established according to edge and gray informa-tion in infrared sequence images by studying gray features on Mean shift algorithm.The model can improvecomputing ability of Mean shift algorithm in the process of tracing target in infrared sequence images.Also,itis shown that our approach can help to improve the ability of gray histogram in descr... |
