Techniques for constructing video playback stimuli fall into five categories. The first three involve manipulating video sequences: (1) edited video is a temporal rearrangement of raw footage, (2) processed video applies global filtering algorithms to edited video, and (3) frame-manipulated video involves manually altering individual frames. The last two, (4) exemplar-based animation and (5) parameter-based animation, are synthetic models derived from visual parameters based on a single exemplar and sample data, respectively. Image-based approaches are straightforward to apply and preserve fine spatiotemporal detail. Synthetic stimuli are desirable when a large number of manipulations are called for and to ensure individual stimuli reflect population characteristics. © Springer-Verlag and ISPA 2000.

Abstract
Techniques for constructing video playback stimuli fall into five categories. The first three involve manipulating video sequences: (1) edited video is a temporal rearrangement of raw footage, (2) processed video applies global filtering algorithms to edited video, and (3) frame-manipulated video involves manually altering individual frames. The last two, (4) exemplar-based animation and (5) parameter-based animation, are synthetic models derived from visual parameters based on a single exemplar and sample data, respectively. Image-based approaches are straightforward to apply and preserve fine spatiotemporal detail. Synthetic stimuli are desirable when a large number of manipulations are called for and to ensure individual stimuli reflect population characteristics. © Springer-Verlag and ISPA 2000.Pubblicazioni consigliate
