Future service robots will need to keep track of the persons in their environment. A number of people tracking systems have been developed for mobile robots, but it is currently impossible to make objective comparisons of their performance. This paper presents a comprehensive, quantitative evaluation of a state-of-the-art people tracking system for a mobile robot in an office environment, for b...

The sequence counting the number of unique tournaments with n people is the same as the sequence counting non-tracking binary strings corresponding to n − 2 radar observations with the tracking rule “3 out of 5 with loss 2.” This fact allows us to build a bijection between unique tournaments and non-tracking binary strings.

Monitoring of human activity requires people to be tracked as they move through the scene. Every tracking method requires object detection. We proposed a new method for detection and tracking of multiple moving objects under static background, based on motion detection, background subtraction using canny edge detection with edge difference between consecutives frames. Keywords—motion detection;...

The abundant choices offered by digital media have raised concerns that audience behavior in news consumption might become polarized into people either aggressively seeking out or avoiding the news. Despite growing evidence to that effect, there is no research that precisely measures exposure to news over a period of years. This study assesses TV news consumption by analyzing respondent-level “...

Do People Seek to Maximize Their Subjective Well‐Being?* In a new survey we ask respondents, after a standard Subjective Well‐Being (SWB) question, if they can think of changes in their lives that would improve their SWB score. If the SWB score is just one argument among others in the respondents’ goals in life, they should easily find ways to improve it, at the expense of other dimensions they...

People counting is a challenging task with many applications. We propose a method with a fixed stereo camera that is based on projecting a template onto the depth image. The method was tested on a challenging outdoor dataset with good results and runs in real time.

On the basis of goal/expectation theory, it was predicted that just as in interpersonal relationships, cooperation in social dilemma groups would increase only if both trust was high and group members had a common goal of cooperation. Introducing new measures of both these two processes to the social dilemma arena, the goal of mutual cooperation was assessed by the process of self–other merging...

The author examines the empirical, methodological, theoretical, and practical contributions of the six studies in this special issue on eye tracking as a tool to study and enhance multimedia learning. The design of learning environments involving graphics should be consistent with a research-based theory of how people learn and evidence-based principles of how to help people learn. Research usi...

This paper presents a solution to the problem of tracking people within crowded scenes. The aim is to maintain individual object identity through a crowded scene which contains complex interactions and heavy occlusions of people. Our approach uses the strengths of two separate methods; a global object detector and a localised frame by frame tracker. A temporal relationship model of torso detect...

Searching and tracking people in crowded urban areas where they can be occluded by static or dynamic obstacles is an important behavior for social robots which assist humans in urban outdoor environments. In this work, we propose a method that can handle in real-time searching and tracking people using a Highest Belief Particle Filter Searcher and Tracker. It makes use of a modified Particle Fi...
