  • Decentralized Particle Filtering for Joint Individual-Group tracking

    A major challenge in computer vision is the task of tracking groups of people in surveillance scenarios, since groups are structured entities, subjected to repeated split and merge events. Our solution presented in "Decentralized Particle Filtering for Joint Individual-Group tracking", Loris Bazzani, Marco Cristani, and Vittorio Murino, CVPR 2012 is a joint individual-group tracking framework, inspired by a recent technique dubbed decentralized particle filtering. The proposed strategy factorizes the joint individual-group state space in two dependent subspaces where individuals and groups share the knowledge of the joint individual-group distribution. In practice, we establish a tight relation of mutual support between the modeling of individuals and that of groups, promoting the idea t...

    The Prima Attentionnal Model predicts people's visual attention from their tracked positions in a room. A person's attention is modeled by an ellipse computed from his motion vector. When multiple ellipses overlap, persons share a common area of visual attention, thus a new group is detected. The processing is done in real-time.

ADAS commonly involve adaptive cruise control, collision avoidance, lane change assistance, traffic sign recognition, and parking assistance with the ultimate goal of producing a fully autonomous vehicle.

In this talk, I will focus on people aggregations at several densities, addressing first the detection and tracking of groups, while also extending the analysis to their behavior/activities. Besides, a large mass of people, a crowd, is also an interesting entity to manage, especially in public events where the level of crowdness may impact in the safety of the people. A crowd cannot be considered a group with a large number of people and, depending on its density, may require different specific techniques to monitor its behavior. I will also address crowd behavior analysis issues, especially dealing with crowd "normality" as opposed to the detection and localization of "abnormalities", as well as the recognition of specific threatening events, like panic and violence.

So for a few minutes there was tension while the group was in the circle but there was no aggression (from the indignados). Meanwhile they (rightist) lit a flare and threw it at people, beat people with the flags they were carrying and after the clashes the police intervened and separated them." 9. Tilt up of drummer leading protest march 10. Various of protesters (supporters of the Indignados) marching STORYLINE: Police intervened during a protest in Lisbon on Saturday after members of a right-wing Portuguese nationalist group clashed with supporters of the left-wing "indignados" group, who organised a march against austerity measures taken by the Portuguese government. Protesters, believed to be members of the right wing group, beat other protesters with flags and lit a flare in the middle of the crowd. No injuries were reported. Police then formed lines to prevent the opposing groups from attacking each other. "For a few minutes there was tension," one leftist protester Gonzalo said. Thousands of protesters eventually marched to parliament, chanting slogans against the so-called Troika of International Monetary Fund, European Central Bank and European Commission. Portugal is locked into a three-year program of debt-reduction measures in return for a financial rescue package from its European partners and the International Monetary Fund. The austerity measures adopted in return for a 78 billion euro (104 billion US dollars) international bailout include higher taxes, a reduction in benefits to some workers and cuts to welfare entitlements. The marchers were mainly "Indignados"; unemployed, but often highly educated young people, who are trying and failing to find work.

A popular GPS based app called Waze has come under fire from police groups as it allows drivers to pinpoint the location of cops and report police sightings to others on the road.

Police unions are now arguing that the technology is putting their officers at risk, particularly in the wake of increased attacks on officers following heightened publicity concerning cases of police brutality. Of course, when it comes to police using similar technology to track and monitor citizens, it’s an entirely different matter. Safety and privacy go out the window in such cases. Most recently, it was revealed that police departments across the United States are now using a program that mines Internet comments and social media posts to determine the “threat score” of a suspect before cops arrive on the scene. Reuters reports that law enforcement authorities have utilized an application called Beware since 2012 that takes just seconds to crawl billions of records in commercial and public databases to assign a threat rating to an individual – green, yellow or red. -~-~~-~~~-~~-~- Please watch: "Hillary Uses Dallas Tragedy As a Decoy" https://www.youtube.com/watch?v=dfF1SmplWYY -~-~~-~~~-~~-~-

Reliable scene analysis, under varying conditions, is an essential task in nearly any assistance or autonomous system application, and advanced driver assistance systems (ADAS) are no exception. ADAS commonly involve adaptive cruise control, collision avoidance, lane change assistance, traffic sign recognition, and parking assistance with the ultimate goal of producing a fully autonomous vehicle. This video addresses detection and tracking of moving objects within the context of ADAS. We use a multisensor setup consisting of a radar and a stereo camera mounted on top of a vehicle. We propose to model the sensors uncertainty in polar coordinates on Lie Groups and perform the objects state filtering on Lie groups, specifically, on the product of two special Euclidean groups, i.e., SE(2)xSE(2). To this end, we derive the designed filter within the framework of the extended Kalman filter on Lie groups. We assert that the proposed approach results with more accurate uncertainty modeling, since used sensors exhibit contrasting measurement uncertainty characteristics and the predicted target motions result with banana-shaped uncertainty contours. We believe that accurate uncertainty modeling is an important ADAS topic, especially when safety applications are concerned. To solve the multitarget tracking problem, we use the joint integrated probabilistic data association filter and present necessary modifications in order to use it on Lie groups. The proposed approach is tested on a real-world dataset collected with the described multisensor setup in urban traffic scenarios.

August 2005 Professor Roberto Cipolla and Gabriel Brostow at the Department of Engineering are working on a project to detect and track individuals in crowd situations. Roberto and Gabriel met with London Transport and West Anglia Great Northern Railway (Wagn), who have different reasons to need to detect and track people in crowds. London Underground use cameras at each of their stations to watch their passengers. The cameras are filtered to some extent; if no one is moving, those cameras are not shown on the monitoring screens. Hundreds of cameras are monitored by staff watching the images, as they switch from one camera to the next. It is impossible to have the manpower to observe all these cameras closely enough to watch for all suicide attempts. Approximately two thirds of suicide attempts are stopped by Underground staff. Tracking individuals more efficiently in crowd situations could improve this figure. Ian Legg of Wagn needs information about when people travel. People buy tickets and may use them that day or the following month. Planning the number of compartments on each train and when to run trains would be more accurate if detailed pedestrian-traffic information was available. In both scenarios people counting is required. There have been approaches to tracking more than one person at a time. One method was successful at tracking three people. More recently there has been success at tracking up to 33 people. But crowds are often much larger. A high level model for detecting one person would portray the person as a 'stick-figure' model and the camera would be looking for the body parts in relation to one another. If the camera detected these body parts in the correct order, the object is recorded as a person. Predictably, to detect people in crowd situations, this high level model was tried but it does not transfer very well. In a crowd you may only see the top of a head or maybe a torso. There is a need for accurate people detection in order to be able to move to the next step of tracking those people. There is a method of detecting features based on recording each point where light meets dark. Such corner detection is a standard algorithm. Video clip shows how features on people have been detected using this method. Video clip 2 shows how a new algorithm clusters the corner features, giving collections of dots that represent individuals. The dots are joined depending upon their proximity to one another and their coherent motion. The method can fail at times, for example, detecting two people as one when they are moving in unison like soldiers. If a person has a backpack or a rolling suitcase with them, the motion of these items may be slightly different to that of the pedestrian, and the luggage may be recorded as a separate person. Another of the collaborators in this research is Niccolò Caderni of Legion International Ltd. Legion simulates how massive numbers of pedestrians would move within a public venue such as a transport terminal or sports stadium, footstep by footstep. Detailed models of how people walk and interact in crowds and in open spaces underpin their software. Legion simulations provide an understanding of crowd behaviour which substantially impact on the design and operation of crowded places. It is the algorithms for learning people-traffic models from real world video footage of crowds that Gabriel and his team are refining.

I ( JJ Johnson ) am a former active duty USAF SERE Instructor. What is a SERE Instructor ? SERE stands for Survival Evasion Resistance and Escape. Basically it was a position that taught combat Wilderness Survival techniques to USAF aircrew members in the mountains North of Spokane Washington near Fairchild AFB. I am also the owner and author of http://www.RealitySurvival.Com. I have worked for the DoD in various positions for about 17 years now. I am an avid outdoorsman, hunter, shooter, and gear reviewer, a prepper, a Christian and a conservative constitutionalist.
