In this paper, a new approach of muhi-modality image registration is represented with not only image intensity, but also features describing image structure. There are two novelties in the proposed method. Firstly, instead of standard mutual information ( MI ) based on joint intensity histogram, regional mutual information ( RMI ) is employed, which allows neighborhood information to be taken into account. Secondly, a new feature images obtained by means of phase congruency are invariants to brightness or contrast changes. By incorporating these features and intensity into RMI, we can combine the aspects of both structural and neighborhood information together, which offers a more robust and a high level of registration accuracy. 展开更多

Women in leadership value supports from their organizations. Pro-social outcomes of relationship competence are mediated by the development of empathy, collaborative approaches to conflict, self-disclosure, and social interest (Jogulu & Wood, 2006). Decision-making perspectives have uncertainty as the sole reason for organizational leaders to search for additional relevant information to solidify or clarify the information at the leader's disposal. A phenomenological qualitative research study which explored the preferred style of leadership based on three leadership and decision-making styles is presented in this paper1. The researcher gathered insights into the lived experiences of like-minded sample of respondents from the research population as they described their leadership and decisionmaking experiences within their organizations. 展开更多
