Better Feature Tracking Through Subspace Constraints

Feature tracking in video is a crucial task in computer vision. Usually, the tracking problem is handled one feature at a time, using a single-feature tracker like the Kanade-Lucas-Tomasi algorithm, or one of its derivatives. While this approach works quite well when dealing with high-quality video and "strong" features, it often falters when faced with dark and noisy video containing low-quality features. We present a framework for jointly tracking a set of features, which enables sharing information between the different features in the scene. We show that our method can be employed to track features for both rigid and nonrigid motions (possibly of few moving bodies) even when some features are occluded. Furthermore, it can be used to significantly improve tracking results in poorly-lit scenes (where there is a mix of good and bad features). Our approach does not require direct modeling of the structure or the motion of the scene, and runs in real time on a single CPU core.Comment: 8 pages, 2 figures. CVPR 201

Configurations of Leadership Traits and Their Relation to Performance Ratings: A Person-Oriented Approach

The study of traits has re-emerged in the leadership literature despite its checkered past. There is now ample evidence that a variety of individual traits consistently relate to leadership effectiveness. Nonetheless, enormous ambiguity remains regarding the patterning of these traits within leaders and the implications of the various interactions among traits. A major contributor to these issues has been the failure to examine these traits within their founding theoretical context, as elements operating simultaneously as a configural system within the individual. Thus, this study examines the configurations of leadership traits in a sample of middle and upper-level managers. The main purposes of this paper are: 1) to describe clusters of within-person trait patterns in a sample of managers, and 2) to evaluate the extent to which these cluster profiles are related to performance ratings from a 360-degree feedback instrument and an assessment center. Results identified four stable clusters of managers based on the similarity of their leader trait patterns. The profile of each cluster was described and the following labels were provided: Action-Oriented Drivers, Interpersonal Achievers, Steadfast Introverts, and Apathetic Stoics. As hypothesized, these clustered displayed differences in both assessment center and multisource feedback ratings of leadership performance. For the most part, Interpersonal Achievers and Steadfast Introverts had the highest performance ratings across all dimensions and sources; however, a few interesting exceptions were revealed. Overall, results support the general premises of the person-oriented approach based on holistic interactionism theory. That is, a limited number of common trait patterns can be identified and used to describe individuals in leadership positions. In addition, based on the results of this study trait patterns assessed via a person-oriented approach are related to leadership performance and often provide a more precise explanation of leadership ratings than do individual or additive trait effects

The matching law

This article introduces the quantitative analysis of choice behavior by describing a number of equations developed over the years to describe the relation between the allocation of behavior under concurrent schedules of reinforcement and the consequences received for alternative responses. Direct proportionality between rate of responding and rate of reinforcement was observed in early studies, suggesting that behavioral output matched environmental input in a mathematical sense. This relation is termed "strict matching," and the equation that describes it is referred to as "the matching law." Later data showed systematic departures from strict matching, and a generalized version of the matching equation is now used to describe such data. This equation, referred to as "the generalized matching equation," also describes data that follow strict matching. It has become convention to refer to either of these equations as "the matching law." Empirical support for the matching law is briefly summarized, as is the applied and practical significance of matching analyses
