    摘要： A packet mapper prioritizes streams of data packets in a computer network, each data packet having a packet header containing feature values descriptive of the data packet. The packet mapper includes a mapping table that associates application-related features with network-reserved feature values from a range of feature values reserved for use by selected network data packet streams, and a feature value mapper that performs at least one of (i) in each packet header having an application-related feature value associated with a network-reserved feature value, substituting the associated network-reserved feature value for the application-related feature value, and (ii) in each packet header having a network-reserved feature value associated with an application-related feature value, substituting the associated application-related feature value for the network-reserved feature value.

    摘要： An arrangement of discrete objects is analyzed. First and second characteristics are extracted from an actual arrangement of discrete objects and an ideal arrangement of points, respectively, and the first and second characteristics are compared. Each characteristic is invariant, to within an angular constant, under an affine transformation of the respective arrangement.

    摘要： Pixels of an image are classified (e.g., into foreground and background pixels). In a set of possible values for the pixels, each value is able to serve as a threshold for classifying the pixels. From among the set, a value is selected for the threshold that causes the classification of the pixels to emphasize a characteristic of the image.

    摘要： A graphical user interface for a computer program enables a user to define a model representing a predefined ideal pattern of objects, the model being useful in analyzing an image of an actual pattern of discrete objects with respect to the model. In the interface, a fragment of the ideal pattern of objects is displayed, the displayed fragment including a graphical indicator of a key distance between objects in the fragment. A device which is visually associated in the fragment with the indicator enables the user to specify a value for the distance. The interface also includes a displayed image representing the pattern of objects, and an interactive device that enables a user to turn on or turn off an object in the image as an indication of its inclusion or exclusion in the pattern.

    摘要： The disclosure concerns an augmented reality method in which visual information concerning a real-world object, structure or environment is gathered and a deformation operation is performed on that visual information to generate virtual content that may be displayed in place of, or additionally to, real-time captured image content of the real-world object, structure or environment. Some particular embodiments concern the sharing of visual environment data and/or information characterizing the deformation operation between client devices.
