Description: We propose a novel approach for head tracking, which combines particle filters with Isomap. The particle filter works on the low-dimensional embedding of training images. It indexes into the Isomap with its state variables to find the closest template for each particle. The most weighted particle approximates the location of head. We develop a synthetic video sequence to test our technique. The results we get show that the tracker tracks the head which changes position, poses and lighting conditions. -We propose a novel approach for head tracking, which combines particle filters with Isomap.

Description: An unsatisfactory property of particle filters is that they
may become inefficient when the observation noise is low.
In this paper we consider a simple-to-implement particle filter,
called ‘LIS-based particle filter’, whose aim is to overcome
the above mentioned weakness. LIS-based particle
filters sample the particles in a two-stage process that uses
information of the most recent observation, too. Experiments
with the standard bearings-only tracking problem indicate
that the proposed new particle filter method is indeed
a viable alternative to other methods. Platform: |

Description: a real-time 3D pointing gesture
recognition algorithm for natural human-robot interaction
(HRI). The recognition errors in previous pointing gesture
recognition algorithms are mainly caused by the low performance
of the hands tracking module and by the unreliability
of the direction estimate itself, therefore our proposed algorithm
uses 3D particle filter for achieving reliability in hand
tracking and cascade hidden Markov model (HMM) for a
robust estimate for the pointing direction. When someone
enters the field of view of the camera, his or her face and
two hands are located and tracked using the particle filters.
The first stage HMM takes the hand position estimate and
maps it to a more accurate position by modeling the kinematic
characteristics of finger pointing. Platform: |

dos下启动的方式是：进入本程序的目录下，输入"objecttracking E:\\……\\……\\***.avi"。本命令有两部分组成objecttracking
是我们的应用程序名， E:\\……\\……\\***.avi是你要打开的视频的全路径，注意是两个“\\”。
2、应用程序目录下，已经有所有的动态库，可直接运行程序。但是想编译源文件工程，需将里面的库复制到工程目录下。
3、希望对你的学习有所帮助， 祝好。-1, the program needs to start in dos, or the default program to open the next panel called soccer.avi E video file, you can modify the name of a video file, on the E-under dos way to start: Go This program directory, enter " objecttracking E: \ \ ... ... \ \ ... ... \ \***. avi" . This command has two parts objecttracking is our application name, E: \ \ ... ... \ \ ... ... \ \***. avi video you want to open the full path, note the two " \ \." 2, the application directory has all the dynamic library can be directly run the program. But would like to compile the source file project, to be inside the library will be copied to the project directory. 3, want to help you learn, I wish well. Platform: |

Description: 粒子滤波理论是近年来跟踪领域的热门研究课题。在该领域，传统的卡尔曼（Kalman）滤波器是非常经典的运动目标跟踪工具。然而经典亦有其弊端，卡尔曼滤波对于非线性及非高斯环境下的工作能力相当无力。为解决这一问题，本文提出了一种基于粒子滤波的目标跟踪方法。其核心为以粒子(一种随机样本，携带权值)来表示后验概率密度，从而得到基于物理模型的近似最优数值解，其优点在于能在追踪的过程中实现更高的精度和更快的收敛速度等。粒子滤波通过加权计算这些带有权重的随机样本来得到目标的近似的运动状态，因此对于非高斯和非线性的环境有着较强的鲁棒性（对特性或参数扰动的不敏感性）。本文将粒子滤波运用于视频跟踪，与传统卡尔曼滤波器进行对比实验，通过实验结果进一步说明粒子滤波对卡尔曼滤波的优势，因此可以广泛的替代传统卡尔曼滤波器，应用于各个跟踪系统中。-Because in non-linear non-Gaussian environment the performance of traditional Kalman Filter in tracking of moving targets is very poor, the paper uses particle filter to track the moving target. Particle filter does not involve linearization around current estimates but rather represent the desired distributions by discrete random measures, which are composed of weighted particles. It has a high accuracy and a rapid convergence. The theory of target tracking based on particle filter is to use these weighted particles to estimate the states of targets. The simulation results of the target model show that in the non-linear non-Gaussian environment, the performance of the particle filter is better than extended Kalman Filter. Finally, we use the particle filter in video tracking, the experimental results further show that in the non-linear non-Gaussian environment the particle filter has a better tracking performance. Particle filter technology can be widely used for air to air, air-groun Platform: |
