Identifying a transition between cameras, retrieving parameters of a first set of viewing configurations, providing 3D video representations representing the scene at several sets of viewing configurations different from the first set of viewing configurations, and generating an integrated video stream enabling 3D display of the scene by integration of at least two video streams having respective sets of viewing configurations, which are mutually different. Another provided process is for synthesizing an image of an object from a first image, captured by a certain camera at a first viewing configuration. Assigning a 3D model to a portion of a segmented object, calculating a modified image of the portion of the object from a viewing configuration different from the first viewing configuration, and embedding the modified image in a frame for stereoscopy.

摘要： It is provided a method for generating a 3D representation of a scene, initially represented by a first video stream captured by a certain camera at a first set of viewing configurations. The method includes providing video streams compatible with capturing the scene by cameras, and generating an integrated video stream enabling three-dimensional display of the scene by integration of two video streams. The method includes calculating parameters characterizing a viewing configuration by analysis of elements having known geometrical parameters. The scene may be a sport scene which a playing field, a group of on-field objects and a group of background objects. The method includes segmenting a frame to those portions, separately associating each portion to the different viewing configuration, and merging them into a single frame. Also, the method may include calculating of on-field footing locations of on-field objects, computing new locations in a new frame, and transforming the on-field objects to the respective frame as a 2D object. Furthermore, the method may include synthesizing at on-field objects by segmenting portions of the object from respective frames of the first video stream, stitching the portions together and rendering the stitched object within a synthesized frame.

摘要： A method for selecting at least one message from a playlist including a plurality of messages to be played by a message playing device to an exposed audience, each message directed to a target audience. The method comprises choosing a utility function, depending on one or more audience parameters, for each of the messages, periodically measuring the audience parameters pertaining to the exposed audience, calculating utility for each of the messages using the utility function, based on the audience parameters as periodically measured, and selecting a message to play from the playlist based on a cumulative gain attributed to each message from the playlist that has played, wherein the gain is updated with respect to the calculated utility for that message. Other methods and systems are also disclosed and claimed.

摘要： A method of selecting key-frames (230) from a video sequence (210, 215) by comparing each frame in the video sequence with respect to its preceding and subsequent key-frames for redundancy where the comparison involves region and motion analysis. The video sequence is optionally pre-processed to detect graphic overlay. The key-frame set is optionally post-processed (250) to optimize the resulting set for face or other object recognition.
