摘要： A method for propagating user-provided foreground-background constraint information for a first video frame to subsequent frames allows extraction of moving foreground objects with minimal user interaction. Video matting is performed wherein constraints derived from user input with respect to a first frame are propagated to subsequent frames using the estimated alpha matte of each frame. The matte of a frame is processed in order to arrive at a rough foreground-background segmentation which is then used for estimating the matte of the next frame. At each frame, the propagated constraints are used by an image matting method for estimating the corresponding matte which is in turn used for propagating the constraints to the next frame, and so on.

摘要： Several implementations relate to view synthesis with heuristic view merging for 3D Video (3DV) applications. According to one aspect, a first candidate pixel from a first warped reference view and a second candidate pixel from a second warped reference view are assessed based on at least one of a backward synthesis process to assess a quality of the first and second candidate pixels, a hole distribution around the first and second candidate pixels, or on an amount of energy around the first and second candidate pixels above a specified frequency. The assessing occurs as part of merging at least the first and second warped reference views into a signal synthesized view. Based on the assessing, a result is determined for a given target pixel in the single synthesized view. The result may be determining a value for the given target pixel, or marking the given target pixel as a hole.

摘要： Various implementations are described. Several implementations relate to view synthesis with boundary-splatting for 3D Video (3DV) applications. According to one aspect, pixels in a warped reference view are splatted based on whether the pixels are within a specified distance from one or more depth boundaries. Such splatting may result in one or more of reducing pinholes around the one or more boundaries or mitigating a loss of high frequency details in non-boundary locations.

摘要： Various implementations are described. Several implementations relate to view synthesis with heuristic view blending for 3D Video (3DV) applications. According to one aspect, at least one reference picture, or a portion thereof, is warped from at least one reference view location to a virtual view location to produce at least one warped reference. A first candidate pixel and a second candidate pixel are identified in the at least one warped reference. The first candidate pixel and the second candidate pixel are candidates for a target pixel location in a virtual picture from the virtual view location. A value for a pixel at the target pixel location is determined based on values of the first and second candidate pixels.

摘要： One particular automatic parameter estimation method and apparatus estimates low level filtering parameters from one or more user controlled high-level filtering parameters. The high level filtering parameters are strength and quality, where strength indicates how much noise reduction will be performed, and quality indicates a tolerance which controls the balance between filtering uniformity and loss of detail. The low level filtering parameters that can be estimated include the spatial neighborhood and/or temporal neighborhood size from which pixel candidates are selected, and thresholds used to verify the 'goodness' of the spatially or temporally predicted candidate pixels. More generally, a criterion for filtering digital image data is accessed (902), and a value is determined (904) for a parameter for use in filtering digital image data, the value being determined based on whether the value results in the criterion being satisfied for at least a portion of a digital image.

摘要： One or more implementations access (400) a digital image containing one or more bands. Adjacent bands of the one or more bands have a difference in color resulting in a contour between the adjacent bands. The one or more implementations apply (405) an algorithm to at least a portion of the digital image for reducing visibility of a contour. The algorithm is based on a value representing the fraction of pixels in a region of the digital image having a particular color value.

摘要： A method for accurately and robustly detecting field lines in an image, such as a frame of a sports video, includes: convolving the image with a Laplacian operator to generate a Laplacian image emphasizing likely line pixels; removing non-playfield related pixels from the Laplacian image, including pixels lying outside of the playfield and pixels representing players within the playfield; contrast stretching the resultant Laplacian image; iteratively applying a Hough transform to the contrast-stretched Laplacian image to detect lines, wherein each iteration results in the detection of one or more field lines which are removed prior to the next iteration, thus reducing the complexity of the next iteration; identifying fragments along each field line detected; filling gaps in the field lines, wherein the gaps are analyzed so that only those gaps that are not likely due to occlusion by players or other non-line objects are filled; and providing a binary mask indicating the pixels representing field lines.
