Abstract:The Gaussian mixture probability hypothesis density filter (GM-PHD Filter) was proposed recently for jointly estimating the time-varying number of targets and their states from a noisy sequence of sets of measurements which may have missed detections and false alarms.

Gaussian mixture (GM) PHD filter. expand all in page. Description. The gmphd object is a filter that implements the probability hypothesis density (PHD) using a mixture of Gaussian components. The filter assumes the target states are Gaussian and represents these states using a mixture of Gaussian components. You can use a gmphd filter to track extended objects or point targets. In tracking.
Subsequently, several researchers enhanced the PHD filter by designing the particle PHD filter (also known as the SMC-PHD) suitable for nonlinear and non-Gaussian conditions (5, 6) and the Gaussian mixture PHD (GM-PHD) filter suitable for linear Gaussian condition (7, 8). However, The PHD recursion propagates cardinality information with the mean of the cardinality distribution. It effectively.
The N-type GM-PHD filter degrades to N GM-PHD filters when we set the probabilities of confusion to 0.0 i.e. no target confusions. However, if each target is regarded as a type, the N-type GM-PHD filter is used as a labeler of each target i.e. it discriminates those targets from frame to frame whether or not confusions between targets exists rather than simply degrading to N standard GM-PHD.
A GM-PHD filter is used for pedestrian tracking in a crowd surveillance application. The purpose is to keep track of the different groups over time as well as to represent the shape of the groups and the number of people within the groups.
The Gaussian Mixure Probability Hypothesis Density (GM-PHD) Multi-target Tracker was developed as an extension to the GM-PHD filter to provide track continuity. The algorithm is demonstrated on forward-looking sonar data with clutter and is compared with the results from the Particle PHD filter.

Existing GM-PHD filter based tracking methods are not always able to accurately track the targets when they are in close proximity, especially with noisy detection responses or in a crowded environments. To address this issue, a measurement classification step which combines a confidence score with a gating technique is presented to discard the false measurements and initialise new-born.

GM-PHD Filter for Searching and Tracking an Unknown Number of Targets with a Mobile Sensor with Limited FOV Yoonchang Sung, Student Member, IEEE, and Pratap Tokekar, Member, IEEE Abstract—We study the problem of searching for and tracking a collection of moving targets using a robot with a limited Field-Of-View (FOV) sensor. The actual number of targets present in the environment is not.
When targets show a mildly non-linear dynamic it is generally possible to rely on extensions for the GM-PHD filter using the Extended Kalman filter (EK-PHD) or the Unscented Kalman filter (UK-PHD) or to use the Gaussian Particle Implementations of the PHD filter. Example I. An unknown, varying number of targets move along the line segment (-100,100). The state of the targets consist of.
An adaptation of Gaussian Mixture Probability Hypothesis Density (GM-PHD)filter is described and applied to the acoustic recordings from six odontocete species. From the raw data, spectral peaks are first identified and then GM-PHD filter is used to simultaneously track the whistles’ frequency contours. Overall over 9000 whistles are tracked with a precision of 85% and recall of 71.8%. The.
Filter (GM-PHD Filter) provided a closed form solu-tion to the PHD lter recursion for multiple target tracking (1). The posterior intensity function is es-timated by a sum of weighted Gaussian components whose means, weights and covariances can be propa-gated analytically in time. In particular, the means and covariances are propagated by the Kalman lter. The original Gaussian Mixture PHD lter.

NL Baisa, D Bhowmik, A Wallace. Journal of Visual Communication and Image Representation 55, 464.We use the Gaussian Mixture Probability Hypothesis Density (GM-PHD) filter, a multi-target tracking algorithm, to track the motion of multiple cells over time and to keep track of the lineage of cells as they spawn. We describe a spawning model for the GM-PHD filter as well as modifications to the original GM-PHD algorithm to track lineage. Experimental results are provided illustrating the.
