Depth Map Estimation and Colorization of Anaglyph Images Using Local Color Prior and Reverse Intensity Distribution

In this paper, we present a joint iterative anaglyph stereo matching and colorization framework for obtaining a set of disparity maps and colorized images. Conventional stereo matching algorithms fail when addressing anaglyph images that do not have similar intensities on their two respective view images. To resolve this problem, we propose two novel data costs using local color prior and reverse intensity distribution factor for obtaining accurate depth maps. To colorize an anaglyph image, each pixel in one view is warped to another view using the obtained disparity values of non-occluded regions. A colorization algorithm using optimization is then employed with additional constraint to colorize the remaining occluded regions. Experimental results confirm that the proposed unified framework is robust and produces accurate depth maps and colorized stereo images.National Research Foundation of Korea (Basic Science Research Program (Ministry of Education, NRF-2012R1A1A2009495))National Research Foundation of Korea (Korea government (MSIP), grant No. NRF-2013R1A2A2A01069181

Public service broadcasting in the market place: the BBC and KBS in the 1990s

With the advent of digital era, the broadcasting landscape is radically changing. Technological development, deregulation and globalisation, as well as changes in social structure and lifestyles combine to shift the established broadcasting paradigm. In the broadband communications environment, bandwidth scarcity, the basis of public service broadcasting, is relieved and thus hundreds of channels are available. Audiences once united in their loyalty to public service channels. are now fragmented. In these circumstances, public service broadcasting, which has been regarded as indispensable, is losing its rationale. Public service broadcasters, irrespective of region and country. are forced to battle for viewers and funding, to redraw their mission and range of activities. and to reshape themselves for the digital world. This study explores how the public service broadcasters (the BBC and KBS) of Britain and Korea have been restructuring themselves to adapt to the changing broadcasting environment. It also traces how the concept of public service broadcasting has evolved in Britain and examines the development of Korean broadcasting, proposing that the distorted operation of Korean public service broadcasting directly resulted from that country's history. Finally, it analyses the reasons why broadcasting in Korea has never been operated on principles of public service despite its proclaimed 'public service system' and explores how to secure the public-ness and public interest of Korean public service broadcasting in the future. For this study in-company research at the BBC and KBS was conducted between 1998 and 2003, along with a literature review. During this period over forty senior staff members were also interviewed, representative of both broadcasters

Human needs as predictors for organizational commitment and job involvement: An exploratory empirical study

While the literature on the determinants of organizational commitment (OC) and job involvement (JI) is vast, little has been studied about the impact of human needs. In search for the institutional stars, this study examines whether human needs can serve a predictor for both high OC and high JI. Exploratory empirical results based on quantile regressions suggest that the needs for achievement, belonging, and power are more important than others in predicting OC and JI. In addition, the basic needs profile does not seem different between the institutional star and the average employee, however, differences between the two groups arise from the differences in the intensity of needs. Preliminary evidence also shows that the profile tends to be slightly lower for female workers or senior workers
