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Mean Shift目标跟踪实时性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 ...
Args: image (np.ndarray): matrix represent image with the object to track in it state (np.ndarray): vector of the state of the tracked object Returns: vector of the normalized histogram of the colores in the ROI of the image based on the state """ # get the top-left and bottom-rig...
在本节中,讨论与本文相关的一些方法,主要是相关滤波和粒子滤波。 相关滤波:Different from existing tracking methods based on correlation filters, we propose a multi-task correlation filter to exploit interdependencies among different features to learn their correlation filters jointly. 与现存的基于相关滤波的...

In this paper, we propose a new observation model with optimizing particle filter framework for visual object tracking in the present of occlusion. Most of the existing algorithms are able to track the object only in predefined and well controlled environment. In computer vision research area, it...

To achieve accurate visual object tracking and overcome the difficulties brought by the object deformation, occlusion, and illumination variations, a particle filter for object tracking algorithm based on color local entropy (CLE) is proposed. First we improved the traditional histogram weighted function...
