摘要:
Techniques for generating action keyframes for a fixed-position camera based on the identification of activity in the video, an assessment of the importance of the activity, object recognition in the video, and interaction techniques for seeing more details of the video are presented. In different embodiments of the invention, the importance of activity is determined based on the amount of activity, important locations in the video streams, detected features such as faces, and events from other sensors.
摘要:
Techniques for generating a storyboard are disclosed. In one embodiment of the invention the storyboard is comprised of videos from one or more cameras based on the identification of activity in the video. Various embodiments of the invention include an assessment of the importance of the activity, the creation of a storyboard presentation based on importance and interaction techniques for seeing more details or alternate views of the video. In one embodiment, motion detection is used to determine activity in one or more synchronized video streams. Periods of activity are recognized and assigned importance assessments based on the activity, important locations in the video streams, and events from other sensors. In different embodiments, the interface consists of a storyboard and a map.

Techniques for generating timelines and event logs from one or more fixed-position cameras based on the identification of activity in the video are presented. Various embodiments of the invention include an assessment of the importance of the activity, the creation of a timeline identifying events of interest, and interaction techniques for seeing more details of an event or alternate views of the video. In one embodiment, motion detection is used to determine activity in one or more synchronized video streams. In another embodiment, events are determined based on periods of activity and assigned importance assessments based on the activity, important locations in the video streams, and events from other sensors. In different embodiments, the interface consists of a timeline, event log, and map.
摘要:
A hypervideo summary comprised of multiple levels of related content and appropriate navigational links can be automatically generated from a media file such as a linear video. A number of algorithms and selection criteria can be used to modify how such a summary is generated. Viewers of an automatically-generated hypervideo summary can interactively select the amount of detail displayed for each portion of the summary. This selection can be done by following explicit navigational links, or by changing between media channels that are mapped to the various levels of related content. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
摘要:
Systems and methods recommend documents or directories in an enterprise context by analyzing use proximity in the organizational hierarchy to find similar users. Evidence may be used from different sources to gage the degree of interest a user may have in a document. Such pieces of evidence may include viewing page thumbnails, viewing the document online, or printing, saving, or bookmarking the document. To make managing these different sources of evidence from users related by different degrees tractable, a model may be created where evidence values decay by different amounts over time and are combined with different weights. Additionally, these systems and methods also can make use of the directory structure of the document space to recommend directories as well as individual documents.
摘要:
A 3D graphical user interface includes a two-dimensional ground-plane layout representing the relationship between one or more leaf elements of a tree data structure. The interface further includes at least one building-like structure, each of the at least one building-like structure corresponding to a respective one of the one or more leaf elements. Each of the at least one building-like structure provides a summary of media associated with the respective one of the more leaf elements corresponding to at least one building-like structure.
