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： 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).

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： Systems and methods of generating and using auxiliary information (38) for reconstructing digital images (34) that have processed through print-scan channels (18) are described. Auxiliary information (38), including values of reference pixels, is extracted from an input image (34). Output image data (36) containing a representation of the input image (34) is generated. The auxiliary information (38) is stored in association with the output image data (36). The auxiliary data structure (40) is decoded to produce decoded auxiliary information (48). Scanned image data (44) that is obtained from a hard copy (42) of the output image data (36) is registered and color-corrected based on the decoded auxiliary information (48) to obtain an output image (46) corresponding to a high-quality reconstruction of the input image (34).

摘要： Systems and methods of denoising images (12) are described. In one aspect, spatially-shifted forward transforms (C 1 , C 2 , …, C k ) of an input image (62) are computed. Each forward transform (C 1 , C 2 , …, C k ) is computed based on a denoiser transform Z having an associated transpose Z’, wherein a matrix multiplication between Z and Z’produces a diagonal matrix Λ, Z = F(D), F specifies a mapping from coefficients of D to coefficients of Z, and D substantially corresponds to a frequency-domain transform. The forward transforms (C 1 , C 2 , …, C k ) are denoised based on nonlinear mappings derived from quantization values linked to the input image (62). Spatially-shifted inverse transforms (C’ 1 , C’ 2 , …, C’ k ) of the denoised forward transforms are computed. Each inverse transform (C’ 1 , C’ 2 , …, C’ k ) is computed based on Z and Z’. An output image (40) is computed based on a combination of spatially-shifted inverse transforms (C’ 1 , C’ 2 , …, C’ k ).
