Abstract: The claimed subject matter provides a system and/or a method that facilitates identifying relationships between two or more trade cards. A schema component can implement a portion of user-assisted schema to create a trade card that represents a distillation of a document with document-specific data. A relationship component can identify at least one of a hard link or a soft link associated with the trade card in connection with at least one of a network or one or more trade cards, wherein the hard link is a source that derived the trade card and the soft link is directed toward a disparate trade card with a portion of substantially similar document-specific data.

Abstract: The claimed subject matter provides a system and/or a method that facilitates servicing a portion of a trade card via a web service. A web service can provide a portion of data to enhance a trade card, wherein the portion of data is at least one of a portion of trade card document-specific data, an intelligent gadget, or a feed driven component. A build component can leverage the web service to utilize the portion of data with the trade card.

Abstract: A stereo matching method simultaneously recovers disparities, colors and opacities from input images to reconstruct 3-dimensional surfaces depicted in the input images. The method includes formulating a general disparity space by selecting a projective sampling of a 3D working volume, and then mapping the input images into cells in the general disparity space. After computing statistics on the color samples at each cell, the method computes initial estimates of color and opacity from the statistics (e.g., the mean and variance of the color samples). The method uses opacity to compute visibility and then uses this visibility information to make more accurate estimates by giving samples not visible from a given camera less or no weight. The method uses the initial estimates as input to refining process which tries to match re-projected image layers to the input images.
