    摘要: Disclosed is a method of editing a data stream, the data stream having a first unique identifier of an identifier space and having assigned metadata , the metadata comprising meta information and a metadata link, the meta-data link comprising the first unique identifier and at least one data packet identifier, the method comprising the steps of:

    performing an editing operation on the data stream,
    assigning a second unique identifier of the identifier space to the data stream,
    storing of the first unique identifier for a resolver task,
    using a decision metric for updating of the meta link.

    摘要: A method for hierarchical disparity estimation on an image pair, wherein image pyramids are created (10) by successively downscaling each image of the image pair, and an apparatus (20) configured to perform the method are described. An initial disparity estimator (22) applies (11) a full search on a highest level of the image pyramids to determine initial disparity estimates, the highest level having the lowest resolution. A disparity propagator (23) passes (12) the initial disparity estimates to a next lower level of the image pyramids. An allocator (24) then partitions (13) the pixels of each remaining hierarchy level of the image pyramids into two or more groups of pixels, where each pixel in a group of pixels can be processed independently from remaining pixels of that group of pixels. A disparity estimator (25) estimates (14) disparity values for the pixels of a first group of pixels utilizing disparity estimates from a next higher level of the image pyramids. The disparity estimator (25) further estimates (15) disparity values for the pixels of remaining groups of pixels utilizing disparity estimates from a previously processed group of pixels in that hierarchy level.

    摘要: The use of disk-assisted, dynamic databases is to be optimized. To this end, provision is made for new data intended to update an old stock of data to have a second index, relating to the new data, generated for them (S3), and for said second index to be stored (S4) on the disk storage medium as a supplement to the first index relating to the old stock of data (S1). This allows the number of write access operations to the disk storage medium to be reduced. This is particularly advantageous for optical media, whose useful life can be increased as a result.
