摘要： Embodiments of the present invention describe a collaborative framework for mining of surveillance videos to detect abnormal events, which introduces a two-stage training process to alleviate the high false alarm problem. In the first stage, unsupervised clustering is performed on the segments of the video streams and a set of abnormal events are combined with user feedback to generate a clean training set. In the second stage, the clean training set is used to train a more precise model for the analysis of normal events and the motion detection results from multiple cameras can be cross validated and combined. 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： Embodiments of the present invention introduce a novel technique to analyze and monitor video streams captured from multiple cameras. It highlights the foreground region of the video streams via local alpha blending and displays the videos in an immersive 3-D environment. The spatial arrangement of the displays can be generated by multi-dimensional scaling of the amount of simultaneous motion across different video streams. 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： Embedded Media Markers (EMM) are optical-filter-like overlaid marks that can be printed on a part of a paper document that signify the existence of media associated with that part of the document. Users take a picture of an EMM-signified document patch using a cell phone camera, and the media associated with the EMM-signified document location is retrieved and displayed on the phone. Unlike bar codes, EMMs are nearly transparent and thus do not interfere with the document contents. Retrieval of media associated with an EMM is based on image local features of the captured EMM-signified document patch. A semi-automatically technique places an EMM at a location in a document, in such a way that the EMM encompasses sufficient identification features with minimal disturbance to the original document.

摘要： An adaptive, interactive visual workspace for viewing groups of files based on their relationships. Relationships of files are visualized using iterative refinement of categories through a direct-manipulation graph-based layout. The visual workspace starts with a fully connected graph linking thumbnail images of related files that is then partitioned into neighborhoods in response to a user creating file stacks corresponding to different categories. Normalized spring lengths improve the overall quality of the layout. Different modes for membership in neighborhoods avoid confusing motion of files and help a user to manually organize the workspace. Additionally, retrieved files can be added without having to significantly move the previous files. Different visualization techniques indicate which files are related to each other. Different zoom rates are used for file location, and surrogate sizes allow users to increase the separation between files while still increasing the surrogate sizes.
摘要翻译： 一个自适应的交互式视觉工作区，用于根据他们的关系来查看文件组。 文件的关系通过直接操作图形布局的类别迭代细化进行可视化。 可视化工作区以完全连接的图形开始，将图形相关联的文件链接起来，然后将其分成邻域，以响应用户创建对应于不同类别的文件堆栈。 标准化的弹簧长度提高了布局的整体质量。 用于居民区成员身份的不同模式可避免混淆文件运动，并帮助用户手动组织工作区。 此外，可以添加检索到的文件，而不必显着移动以前的文件。 不同的可视化技术指出哪些文件是相互关联的。 文件位置使用不同的缩放比例，替代尺寸允许用户增加文件之间的间隔，同时仍然增加代理大小。
