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： 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： Systems and methods of reducing artifices in compressed images (12) are described. In one aspect, spatially-shifted forward transforms of the input image (12) are computed to generate respective sets of forward transform coefficients (C 1 , C 2 , …, C K ). Nonlinear transforms (T 1 , T 2 , …, T K ) are applied to the forward transform coefficients of each set (C 1 , C 2 , …, C K ). Inverse transforms (C’ 1 , C’ 2 , …, C’ K )of the sets of nonlinearly transformed forward transform coefficients are computed to generate respective intermediate images (I 1 , I 2 , …, I K ). Respective measures of local spatial intensity variability are computed for pixels of each of the intermediate images (I 1 , I 2 , …, I K ). An output image (40) is computed with pixel values computed based at least in part of the competed measures of the local spatial intensity variability.

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). The auxiliary information (48) may include coded transform coefficient data from which the input image (34) may be reconstructed using the registered and color-corrected output image (46) as side information.

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 ).
