In theory HDR photography generated from exposure sequences is limited to pictures of still scenes preferably taken with the camera mounted on a tripod. Current state-of-the-art HDR imaging software relaxes this limitation by aligning the pictures with affine transformations. However, two pictures cannot be aligned with a single affine transformation if objects in the scene move or the position...

Vision: a computational investigation into the human representation and processing of visual information ,

In rapid serial visual presentation of pictures, an early ERP component shows enlarged negativity over occipital regions for emotional, compared to neutral, pictures. The present study examined the processing of emotional target pictures as a function of the hedonic valence of a preceding prime picture. Dense sensor ERPs were measured while subjects viewed a continuous stream of pleasant, neutr...

Recent work has questioned whether the negativity bias is a distinct component of affective picture processing. The current study was designed to determine whether there are different neural correlates of processing positive and negative pictures using event-related brain potentials. The early posterior negativity and late positive potential were greatest in amplitude for erotic pictures. Parti...

Four experiments revealed arousal-enhanced location memory for pictures. After an incidental encoding task, participants were more likely to remember the locations of positive and negative arousing pictures than the locations of non-arousing pictures, indicating better binding of location to picture. This arousal-enhanced binding effect did not have a cost for the binding of temporally or spati...

I add to the empirical literature on vertical contracting and wholesaler conduct by using retailer entry conditions to infer unobserved choice variables and equilibrium responses to prices and advertising. After estimating the US demand for theatrical motion pictures from 1990–96, I apply these techniques to compare observed outcomes to predictions under various distributorconduct hypotheses. W...

Both recognition and recall of pictures improve as picture presentation time increases and as time between pictures increases. Processing of the pictures, rehearsal and/or encoding, continues after the picture has disappeared, just as for verbal material. Both the results and conclusions stand in contrast to those of Shaffer and Shiffrin.

The Heisenberg, interaction, and Schrödinger pictures of motion are considered in Lagrangian (canonical) quantum field theory. The equations of motion (for state vectors and field operators) are derived for arbitrary Lagrangians which are polynomial or convergent power series in field operators and their first derivatives. The general links between different time-dependent pictures of motion ar...

If one constructs a visual language, it is necessary to have a methodology for constructing the relationship between aspects of the pictures and the corresponding aspects of the application domain. The various methods for specifying Visual Languages emphasize computational aspects, where the semantics of the picture is embedded in the computational setting of the speciication, but they are not ...
