It employs the main principles of professional and ethical journalistic practices. The article argues that NTC coverage for this revolution sometimes goes beyond informing people to other forms of propaganda. It concludes that professional and ethical media performance would better serve the interests of Yemeni audiences, including their desire for bringing change. Moreover, ownership is not the only issue when it comes to free press and the right to communication. However, establishing a stable system for media performance based on consensual rules on one hand, and professionalism and ethics, on the other, is fundamental for media reform in Yemen.展开更多

The interdependence between rotational and translational constraints is considered, and a constraint unscented Kalman filter （CUKF） algorithm is utilized to achieve a smoothly stabilized motion. The method is applied to stabilize each video frame, and the results reveal that the proposed approach improves the stabilization performance in comparison with the trivial approach.展开更多

文摘A motion filtering method is proposed in this paper, which takes into consideration the existence of certain system constraints with respect to the amount of the corrective rotational and translational motions that can be applied on each video frame for stabilization. The interdependence between rotational and translational constraints is considered, and a constraint unscented Kalman filter （CUKF） algorithm is utilized to achieve a smoothly stabilized motion. The method is applied to stabilize each video frame, and the results reveal that the proposed approach improves the stabilization performance in comparison with the trivial approach.
