Particle Filter Object Tracking Visual object tracking is a difficult problem, but in recent years, particle filter-based object trackers have proven to be very effective. Conceptually, a particle filter-based tracker maintains a probability distribution over the state (location, scale, etc.) of the...
粒子滤波Sobel中值二值模式纹理特征颜色特征针对传统粒子滤波目标跟踪算法在光照变化及遮挡情况下跟踪准确性不高的缺陷,提出一种双重特征粒子滤波目标跟踪算法.首先,提出一种融合边缘信息具有抗光性的Sobel中值二值模式特征描述算子,建立视频每帧的纹理直方图;对视频每帧分别提取HSV颜色空间的色度核函数直方图、饱和度核...

Traditional particle filter algorithm needs a large number of particles to show posteriori probability density function of object state, the calculation of this algorithm is large, and the real-time of tracking is poor, so it is hard to track fast and sheltered object accurately. Considering above...
