摘要： An embodiment of a system and method that inserts a virtual image into a sequence of video frames. The method includes capturing geometric characteristics of the sequence of video frames, employing the captured geometric characteristics to define an area of the video frames for insertion of a virtual image, registering a video camera to the captured geometric characteristics, identifying features in the sequence of video frames to identify the defined area of video frames for insertion of the virtual image, and inserting the virtual image in the defined area. Vanishing points are estimated to determine the geometric characteristics, and the virtual image is blended with the area of video frames prior to inserting the virtual image in the defined area.

摘要： An apparatus includes a patch library creator for creating a first patch library from an original version of the picture and a second patch library from a reconstructed version of the picture. Each of the libraries includes a plurality of high resolution replacement patches for replacing one or more pruned blocks during a recovery of a pruned version of the picture. A pruner generates the pruned version from the first patch library, and decides whether to respectively replace original blocks with pruned blocks responsive to a comparison between a first rate-distortion estimate and a second rate-distortion estimate. The estimates are based on both a distortion component and a bitrate component. A metadata generator generates metadata from the second patch library. The metadata is for recovering the pruned version. An encoder encodes the pruned version and the metadata.

摘要： This document describes techniques that label text nodes of a seed site for each of a plurality of verticals. Once a seed site is labeled for a given vertical, the techniques extract features from the labeled text nodes of the seed site. The techniques learn vertical knowledge for the seed site based on the human labels and the extracted features, and adapt the learned vertical knowledge to a new web site to automatically and accurately identify attributes and extract attribute values targeted within a given vertical for structured web data extraction.
