Multiple vantage points of the common operational picture: Supporting International Teamwork
Teamwork Geographic Information Systems Common Operational Picture Large Group Display
2014/12/20
This paper summarizes multiple perspectives of the common operational picture (COP) in military and civilian crisis management domains viewed from three vantage points: historical, conceptual, and pra...
Advertising and Word-of-Mouth in Motion Picture Industry
Advertising Word-of-Mouth Motion Picture Industry
2011/8/8
Motion picture industry is characterized by extensive advertising and word-of-mouth among (potential) consumers. We develop a simple computational model of consumer behavior to study the interaction b...
Advanced Spatial and Temporal Direct Mode for B Picture Coding
Advanced Spatial Temporal Direct Mode
2011/7/24
The direct mode in H.264/AVC can efficiently improve the coding performance of B pictures, since it exploits the spatial or temporal correlation by deriving its motion vector from previously encoded i...
WINDOW-LEVEL RATE CONTROL FOR SMOOTH PICTURE QUALITY AND SMOOTH BUFFER OCCUPANCY
Rate Control Smooth Picture Quality ½ - domain Window Buffer Occupancy
2011/7/24
rate control consists of bit allocation and QPdecision on R-QP model. In bit allocation, target bits is further confined if buffer overflows. Meanwhile, rate controlshould also give as smo...
Until the 1980s, using a computer program meant memorizing a lot of commands and typing them in a line at a time, only to get lines of text back. The graphical user interface, or GUI, changed that. By...
Is a Picture Worth a Thousand Words? The Use of Non-Text Items in Information Systems Research
Picture Worth Thousand Words Non-Text Items Information Systems Research
2009/12/8
The use of non-text items (graphs, graphics and tables) is firmly established in the publishing tradition of information systems research. Non-text images are used to convey complex information in a p...
Concealment of Whole-Picture Loss in Hierarchical B-Picture Scalable Video Coding
Error concealment H.264/AVC hierarchical B-picture motion compensation scalable video coding.
2009/1/16
H.264/AVC scalable video coding (H.264/AVC SVC),as the scalable extension of H.264/AVC, offers the flexible adaptivity in terms of spatial, temporal and SNR scalabilities for the generated bitst...
