摘要： Embodiments of the present invention are directed to a visual-collaborative system enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system comprises a display screen, a camera system, and a projector. The display screen has a first surface and a second surface, and the camera system is positioned to capture images of objects through the display screen. The projector is positioned to project images onto a projection surface of the display screen, wherein the projected images can be observed by viewing the second surface. The system includes a first filter disposed between the camera and the first surface, where the first filter passes light receives by the camera but substantially blocks the light that is produced by the projector.

摘要： A method for levels is described. The method includes the step of determining the affect of flicker in each video frame using a color statistic value of a plurality of captured video frames (120) and determining a flicker frequency from the affect of flicker in each video frame (130). Given the flicker frequency, a video camera exposure frequency is selected that provides diversity in light intensities (140). The video camera exposure control is synchronized to the flicker frequency (150) and also adapted to control the amount of flicker occurring in each video frame to capture a plurality of video frames (160).

摘要： Methods, computer-readable media, and systems are provided for combining multiple video streams. One method for combining the multiple video streams includes extracting a sequence of media frames (224-1/224-2) from presenter (222-1) video and from shared digital rich media (222-2) video (340). The media frame (224-1/224-2) content is analyzed (226) to determine a set of space and time varying alpha values (228/342). A compositing operation (230) is performed to produce the combined video frames (232) based on the content analysis (226/344).

摘要： Various method and system embodiments of the present invention are directed to computational estimation of a tempo for a digitally encoded musical selection. In certain embodiments of the present invention, described below, a short portion of a musical selection is analyzed to determine the tempo of the musical selection. The digitally encoded musical selection sample is computationally transformed to produce a power spectrum corresponding to the sample, in turn transformed to produce a two-dimensional strength-of-onset matrix (618). The two-dimensional strength-of-onset matrix is then transformed (806) into a set of strength-of-onset/time functions (716) for each of a corresponding set of frequency bands (704-707). The strength-of-onset/time functions are then analyzed to find a most reliable onset interval (808, 8100) that is transformed into an estimated tempo returned by the analysis (812).

摘要： Controlling artifacts in video data. Image data of collocated pixels of a plurality of frames of the video data is sampled (310), wherein at least a portion of each of the plurality of frames corresponds to an object that does not move across the plurality of frames. A statistical curve fit is performed (320) on sampled image data of the collocated pixels, wherein the statistical curve fit places less consideration on a sampled collocated pixel that corresponds to movement of an object across the plurality of frames. An adjusted frame is generated (330) based at least in part on at least one parameter of the statistical curve fit.

摘要： A method and apparatus for improving the quality of MPEG video are disclosed. In a preferred embodiment, a group of pictures (GOP) is obtained (101) and decompressed (102), producing an initial decompressed GOP. This initial decompressed GOP is spatially shifted (103) to at least two shift positions. At each shift position, MPEG compression and decompression are applied, producing a resulting decompressed GOP for each shift position. The resulting decompressed GOPs are shifted back (104) to their initial position and combined (105), preferably by averaging, to form an improved GOP.

摘要： Methods, systems, and machine-readable media for processing an input image (22) are described. In one aspect, respective visual features of local input image regions of an input image (22) having a first pixel resolution are analyzed to produce a result (26). Based on the result (26) of analyzing the visual features, reduced-resolution visual representations (30) of corresponding ones of the local input image regions are derived from the input image. A thumbnail image (24) that reflects the arrangements, proportions and local details of the input image (22) having a second pixel resolution lower than the first pixel resolution is produced from the reduced-resolution visual representations (30). The thumbnail image (24) is output.
