Abstract: A method for real-time analytical queries of a documents store is provided. The method includes receiving a query and an access control list associated with a user, the query requesting content managed by a content management system. The method further includes generating an execution plan based on the query and the access control list. The method further includes constraining, based on the execution plan, possible results returned from the query using a content index of a plurality of content items maintained in a repository of the content management system. The constraining includes limiting the at least one processor from adding a content item of the plurality of content items to a permissions-filtered results set based on the access control list identifying the user as not having permission to access the content item. The method further includes aggregating the permissions-filtered results set and returning the aggregated permissions-filtered results set.

Abstract: There is provided a video playback device for providing an interactive environment on a display in response to a user input. The video playback device comprises (1) a memory to store a plurality of images forming a plurality of viewpoints of the interactive environment; a plurality of transition sequences, wherein each of the plurality of transition sequences provides a video transition from one image to another image; and a linking structure linking the plurality of images with the plurality of transition sequences; (2) a processor to determine a direction of movement based on the user input; select a next one of the plurality of transition sequences and a next one of the plurality of images based on the direction of movement and the linking structure; and display the next one of the plurality of transition sequences and the next one of the plurality of images on the display.

Abstract: A method and system for merging metadata with digital images is disclosed, where the digital images are stored as image files having metadata fields associated therewith. The method and system include receiving data uploaded from a remote location, providing a web application to a client device over a network when requested, and transmitting the previously uploaded data to the web application. When an image requires input of metadata on the client device, the uploaded data is displayed on the client device for selection by the user. In response to the user's selection, the selected data is then used to automatically populate the metadata fields associated with the image file.

Abstract: A method and apparatus for de-interlacing a buffer of image data, wherein scan lines from an image sensor have been transferred to the buffer and stored in a group of even scan lines and a group of odd scan lines. The method for de-interlacing the buffer includes providing a first table to indicate current storage locations of each scan line in the buffer and providing a second table to indicate which scan line is currently stored in each storage location. The first table and a temporary line buffer are then used iteratively swap pairs of scan lines that are stored out of numerical order in the buffer, such that after a swap, one of the scan line in the pair is stored in numerical order in the buffer. After each swap, the first table is updated using the second table, and then second table is updated, such that the first and second tables reflect a change of storage locations for the scan lines, whereby the buffer is de-interlaced in place without using a duplicate buffer.

Abstract: A method for displaying an image to a display device is provided. This method includes sequentially the steps of receiving the image in a first data format, performing a white balance correction in combination with a gamma correction for the image in the first data format, performing a color correction in combination with a color space conversion to a second data format for the image, and displaying the image in the second data format to the display device. This method reduces the number of multiplications required in the conversion of an image from the first data format to the second data format. This results in significant savings in CPU time, and more images may be displayed within a certain amount of time.
