Existing methods for incorporating subspace model constraints in shape tracking use only partial information from the measurements and model distribution. We propose a unified framework for robust shape tracking, optimally fusing heteroscedastic uncertainties or noise from measurement, system dynamics, and a subspace model. The resulting nonorthogonal(More)
The description of neurophysiological tools is broken down into psychophysiological tools and neurophysiological tools. For additional details, see Riedl et al. (2010). Eye Tracking Eye tracking tools measure where the eye is looking (eye position) or the eye's motion relative to the head (eye movement) (Shimojo et al. 2003). Eye tracking tools gather data(More)
The Internet has brought consumers increased access to information to make purchase decisions. As markets come closer to perfect information, one of the expected outcomes is an increase in competition. One of the consequences is an increase in the price elasticity of demand, or the percent change in demand due to a percent change in price, because consumers(More)
The segmentation of anatomical structures has been traditionally formulated as a perceptual grouping task, and solved through clustering and variational approaches. However, such strategies require the a priori knowledge to be explicitly defined in the optimization criterion, e.g., "high-gradient border", "smoothness"', or "similar intensity or texture".(More)

Empirical research of consumer online shopping behavior has generally established that risk associated with online shopping is an important factor when consumers consider whether to shop online or in a brick-and-mortar store. Literature also indicates the importance of information search and product evaluation in consumer purchasing decisions. Building on(More)
