    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: A method of identifying a location of a mobile device in a building includes identifying non-overlapping regions in a building. A server collects base station signal strength measurements at a plurality of distinct points in the building, with at least one point in each region. The server trains region classifiers for each region. Each region classifier is configured to compute a probability estimate that the test point is inside the region, using inputs that are signal strength differences. The server receives signal strength measurements from the base stations, taken by a mobile device at an unknown point. The server computes differences in signal strengths between pairs of base stations, and applies the region classifiers to the signal strength differences, thereby estimating the region where the mobile device is located. The server then transmits the estimated region to a user.

    摘要: Described is a system for automatic digital photo orientation detection. We leverage online public photos with great content variation to extract effective features with layout information. Classification proceeds using an approximate nearest neighbors approach which scales well to massive training sets, hardly compromising efficiency. We have tested the method successfully on the largest data set to date of nearly 30,000 Flickr photos as well as both difficult and typical consumer usage scenarios. Though limited data are available for comparison across different systems, the proposed system significantly outperforms a state of the art system on a common data set.

    摘要: The present invention provides a system and method for automatically combining image and audio data to create a multimedia presentation. In one embodiment, audio and image data are received by the system. The audio data includes a list of events that correspond to points of interest in an audio file. The audio data may also include an audio file or audio stream. The received images are then matched to the audio file or stream using the time. In one embodiment, the events represent times within the audio file or stream at which there is a certain feature or characteristic in the audio file. The audio events list may be processed to remove, sort or predict or otherwise generate audio events. Images processing may also occur, and may include image analysis to determine image matching to the event list, deleting images, and processing images to incorporate effects. Image effects may include cropping, panning, zooming and other visual effects.
