基于序贯蒙特卡罗的多线索目标跟踪算法
Object Tracking Algorithm Based on Multi-cue and Sequential Monte Carlo
摘要
颜色直方图对噪声和部分遮挡不敏感,当背景颜色与目标颜色相近时,会影响跟踪效果。本文提出一种有效的基于多线索融合的序贯蒙特卡罗图像序列跟踪方法,采用颜色直方图和边缘直方图与序贯蒙特卡罗算法结合起来进行视频跟踪。颜色直方图和边缘直方图一起构建目标观测似然函数。在序贯蒙特卡罗方法的框架下,采用观测模型函数获取图像序列中目标位置的后验概率分布。实验结果表明,结合图像颜色与边缘特征,在序贯蒙特卡罗的框架下可以取得更为有效和稳健的跟踪效果。
Abstract
The color-based histogram is robust against noise and partial occlusion, but suffers from the presence of the confusing colors in the background. An efficient image sequence tracking method was presented based on multiple cues in Sequential Monte Carlo (SMC). The background-weighted color histogram was combined with edge histogram into SMC for tracking. Color histograms and edge histograms were used to model the object observations likelihoods function. The observations were used to obtain a posterior probability distribution for the location of the object in the sequence images based on SMC. It can be seen from the experiment that the combination of color histogram and edge histogram based on SMC can achieve more robustness and efficient tracking.
