Action recognition is one of the most active research fields in computer vision. This chapter first reviews the action recognition methods in literature from two aspects: action representation and recognition strategy. Then, a novel method for classifying human actions from image sequences is investigated. In this method, each human action is represented by a sequence of shape context features of human silhouette during the action, and a dominant set-based approach is employed to classify the action to the predefined classes. The dominant set-based approach to classification is compared with K-means, mean shift, and Fuzzy-Cmean approaches.

The integralNHof neutral-hydrogen density along the line of sight is determined from the Kootwijk and Sydney surveys. The run ofNHwith galactic longitude agrees well with that of thermal continuous radiation and that of the optical surface brightness of the Milky Way.

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.

Context Features

This study analyzes public hearings about same-sex marriage to show how the contexts that are established for citizens' and legislators' talk make arguments about the issue being disputed. Situated within the traditions of argument studies and discourse analysis, the article explores different meanings of “context.” The study evidences how two sets of context features created positive (or negative) stances toward the issue of same-sex marriage, and shows that how the controversy was formulated and how participation was designed gave distinct advantages to speakers advocating for (or against) same-sex marriage. The final section draws out implications of these legislative choices for citizen presenters and for the officials themselves as the enactors and guardians of democratic process.
