摘要： Various embodiments of methods and apparatus for removing unwanted background color from a border region surrounding a foreground object in an image in order to composite the foreground object of the image with a new background image are described. Embodiments of color decontamination for image compositing may accept an image and an alpha matte corresponding to the image as input. In some embodiments, estimated foreground colors are determined for pixels in a border region between the foreground and the background of the input image. In some embodiments, the input image may be created by down-sampling a higher resolution image and pixels with estimated foreground colors may be up-sampled. In some embodiments, a composite image may be created based on the input image, the alpha matte, the estimated foreground colors of pixels in the border region and a new background image. In some embodiments, a texture preserving luminance blending operation may be performed using the estimated foreground colors for pixels in the border region to create refined foreground colors for pixels in the border region. In some embodiments, a composite image may be created further based on the refined foreground colors for pixels in the border region. In some embodiments, parameters controlling the creation of a composite image may be set in response to user input.

摘要： Methods and apparatus for generating variable-width border masks for objects in input images. Given an input image and an initial binary selection of an object in the image, a variable-width border mask method may be applied to automatically generate an accurate, variable-width border mask for the object. An initial border mask may be generated. An initial foreground probability map may be generated within the initial border mask using a Gaussian Mixture color modeling technique. A geodesic smoothing technique may be applied to the initial foreground probability map to reduce or remove noise. An optimization technique may be applied to optimize the foreground boundary, and a final variable-width border mask may be generated. The variable-width border mask may be used as input to image matting algorithms to generate an accurate alpha mask of the foreground object selected from the input image.

摘要： Methods and apparatus for temporal matte filtering. Temporal matte filtering methods are described that improve the temporal coherence of alpha mattes for a video sequence while maintaining the matte structures on individual frames. The temporal matte filter may implement a level-set-based matte averaging method. In the level-set-based matte averaging method, two or more input alpha mattes are obtained. Level set curves are generated for the two or more alpha mattes. An averaged level set is computed from the two or more level sets according to a distance-transform-based technique. A temporally smoothed alpha matte may then be reconstructed by interpolating pixel alpha values between the inner and outer level set curves of the averaged level set. The alpha mattes can be optionally warped towards a center frame according to an optical flow technique before the averaging operation performed by the temporal matte filter.

摘要： A sharp frame and a blurred frame are detected from among a plurality of frames. A blur kernel is estimated. The blur kernel represents a motion-transform between the sharp frame and the blurred frame. Using the blur kernel, a static region measure for the sharp frame and the blurred frame is estimated. A de-blurred frame is generated by replacing one or more pixels of the blurred frame as indicated by the static region measure.

摘要： Systems, methods, and computer-readable storage media for chatter reduction in video object segmentation using optical flow assisted gaussholding. An optical flow assisted gaussholding method may be applied to segmentation masks generated for a video sequence. For each frame of at least some frames in a video sequence, for each of one or more other frames prior to and one or more other frames after the current frame, optical flow is computed for the other frame in relation to the current frame and used to warp the contour of the segmentation mask of the other frame to generate warped segmentation mask for the other frames. The weighted average of the warpedsegmentation masks and the segmentation mask of the current frame is then computed; this weighted average may be blurred spatially, for example using a Gaussian filter. The initial smoothed mask may be thresholded to produce a binary smoothed mask.

摘要： A method, system, and computer-readable storage medium are disclosed for generating a location-weighted mask based on a color model comprising spatial dimensions. In one embodiment, a selection of at least one pixel in an input image is received, wherein the selection of the at least one pixel comprises a color and a location within the input image. A color model may be determined based on the color and the location of the at least one pixel, wherein the color model comprises one or more truncated Gaussian functions. A mask may be generated based on the color model. The mask may indicate a degree of membership in the mask for each pixel in the input image as a function of a similarity in color to the at least one pixel in the selection and a proximity to the location of the at least one pixel in the selection.
