    摘要： Methods and systems, including computer program products, for determining a plurality of color clusters based on a plurality of pixels associated with a color image, the clusters being fewer than the pixels. A grayscale value for each one of a plurality of points in a color space is determined. Each grayscale value is based on a weighted average of target differences between each point and the clusters. Each of the pixels is associated with one or more of the points. A grayscale value for each pixel is identified based on the grayscale value of the associated one or more points.

    摘要： Methods and apparatus implementing a technique for searching media objects. In general, in one aspect, the technique includes receiving user input specifying a plurality of reference objects (2), defining a set of features for them, and combining the features to generate composite reference information (4) defining criteria for search (6). In general, in another aspect, the technique includes combining object information for a plurality of reference objects to produce composite reference information, comparing (10) the composite reference information to object information for media objects in a collection of media objects, and selecting a media object based upon the comparison.

    摘要： Systems and methods for simulating liquid-on-lens effects may provide an interface through which users can add and/or manipulate fluids on a virtual camera lens. A physically based fluid simulation may simulate the behavior of the fluid as it is deposited on and/or manipulated on the virtual lens, and determine the distribution of the fluid across the lens. A ray tracing technique may be employed to determine how light is refracted through the virtual lens and the fluid, and to render a distorted output image as seen through the lens and the fluid. As the fluid is manipulated, corresponding changes in the image may be displayed in real time. The input image may be an existing single image or a direct camera feed (e.g., of a tablet type device). The user may select a fluid type and/or various fluid properties for the image editing operation.

    摘要： Methods and apparatus, including computer program products, implementing and using techniques for masking and extracting a foreground portion from a background portion of a digital video. An input defining an initial border region is received, which includes a border between a foreground portion and a background portion of an initial digital image in a digital video. A border region for another digital image in the digital video is generated. The initial and automatically generated border regions are used for masking the foreground portion from the background portion in the digital video.
