Augmenting Aerial Earth Maps with Dynamic Information Abstract We introduce methods for augmenting aerial visualizations of Earth (from tools such as Google Earth or Microsoft Virtual Earth) with dynamic information obtained from videos. Our goal is to make Augmented Earth Maps that visualize the live broadcast of dynamic sceneries within a city. We propose different […]
N. Diakopoulos PhD Thesis (2009): Collaborative annotation, analysis, and presentation interfaces for digital video"
Title: Collaborative annotation, analysis, and presentation interfaces for digital video Author: Diakopoulos, Nicholas A. Abstract Information quality corresponds to the degree of excellence in communicating knowledge or intelligence and encompasses aspects of validity, accuracy, reliability, bias, transparency, and comprehensiveness among others. Professional news, public relations, and user generated content alike all have their own subtly different information […]
