摘要： Simultaneous tracking of multiple objects in a sequence of video frames captured by multiple cameras may be accomplished by extracting a foreground elements from a background in a frame, segmenting objects from the foreground surface, tracking objects within the frame, globally tracking positions of objects over time across multiple frames, fusing track data of objects obtained from multiple cameras to infer object positions, and resolving conflicts to estimate most likely object positions over time. Embodiments of the present invention improve substantially over existing trackers by including a technique for extraction of the region of interest that corresponds to a playing field, a technique for segmenting players from the field under varying illuminations, a template matching criteria that does not rely on specific shapes or color coherency of objects but on connected component properties, and techniques for reasoning about occlusions and consolidating tracking data from multiple cameras.

摘要： Camera driven virtual workspace management is disclosed. A digital camera captures an input video stream comprising images of a surrounding environment limited by a field of view of the camera. The input video stream is processed by a handheld computer coupled to the camera. Parameters that define a partial view of a virtual workspace are redefined based upon motion analysis of the input video stream performed by the handheld computer during the processing.

摘要： A method comprises, for a plurality of interpolated pixels in an interpolated video frame, classifying an interpolated pixel of the plurality as one of stationary, moving, covered, and uncovered, and then setting components of the interpolated pixel to components of a previous pixel from a previous video frame, the previous pixel corresponding to the interpolated pixel in the video frame. If the interpolated pixel is uncovered, components of the interpolated pixel are set to components of a current pixel from a current video frame if the interpolated pixel is uncovered, the current pixel corresponding to the interpolated pixel in the video frame. If the interpolated pixel is moving, the interpolated pixel is set to a function of the current pixel and the previous pixel.

摘要： Interpolation of a new frame between a previous frame and a current frame of a video stream by motion compensated frame rate upsampling. The interpolation method includes identifying nodes and edges of objects such as triangles present in the previous frame, constructing a superimposed triangular mesh based on the identified nodes and edges, estimating displacement such nodes in the superimposed triangular mesh from the previous frame with respect to the current frame, and rendering the new frame based on the estimated displacement of nodes. Additionally, pixels of the previous frame and the current frame may be classified according to whether a pixel's value has changed from the previous frame to the current frame. This classification may be used during rendering to reduce overall processing time. Pixel-based forward motion estimation may be used to estimate motion of pixels between the previous frame and the current frame and the estimated motion may be used in estimating node displacement.
