A Novel and Effective Short Track Speed Skating Tracking System

This dissertation proposes a novel and effective system for tracking high-speed skaters. A novel registration method is employed to automatically discover key frames to build the panorama. Then, the homography between a frame and the real world rink can be generated accordingly. Aimed at several challenging tracking problems of short track skating, a novel multiple-objects tracking approach is proposed which includes: Gaussian mixture models (GMMs), evolving templates, constrained dynamical model, fuzzy model, multiple templates initialization, and evolution. The outputs of the system include spatialtemporal trajectories, velocity analysis, and 2D reconstruction animations. The tracking accuracy is about 10 cm (2 pixels). Such information is invaluable for sports experts. Experimental results demonstrate the effectiveness and robustness of the proposed system

Ajami in West Africa

West Africans throughout the region have creatively adapted the Arabic script to write non-Arabic languages, a form of literacy known as Ajami which remains widespread today despite little or no government support. The variety of methods used to extend the Arabic script to fit other phonological systems are of particular interest: methods that appear unmotivated from a purely linguistic perspective can readily be explained as rational adaptations to the parallel educational system in which Ajami is typically learned, an issue often not taken into account in orthography planning
