  • Patent number: 8335392
    Abstract: A method for reducing image artifacts in an image that includes a number of pixels each of which includes at least one video information value, includes generating a plurality of filter coefficients for at least some of the pixels of the image, on the basis of which the video information values of the pixels can be reconstructed. Artifact detection is performed to detect artifact regions within the image. At least some filter coefficients of those pixels that lie within the artifact regions are modified to generate modified filter coefficients. The video information values are synthesized using the filter coefficients, the modified filter coefficients being employed for the synthesis for pixels lying within the artifact regions.

  • Patent number: 8037405
    Abstract: A method for improving functionality of a binary representation of an XML-based content description, wherein a structure of any instance of an XML-document corresponds to a tree-like data structure including a plurality of tree nodes, is provided. The method includes providing that each tree node represents an element of the content description and has a structure which is defined in a schema; providing the tree nodes in binary representation with tree branch codes; providing that the respective tree branch code has a schema branch code; extending an existing schema by utilizing unused schema branch codes in a tree node for extensions with new elements until the unused schema branch codes are all used up, and increasing a bit length of the schema branch code as necessary; and communicating a bit length change to a decoder for correctly decoding the content description in the binary representation.

  • Patent number: 8024366
    Abstract: A schema definition, which is known to the encoder and to the decoder or transmitted from the encoder to the decoder, specifies information for calculating code concerning the elements or data types contained in the name subspace and enabling this information to be clearly assigned in this manner to each code in the name subspace. Only a portion of the entire name space including the number of the elements or data types lacking for the code calculation have to be transmitted for the configuration of a code which generally means a significantly smaller volume of data than the volume of data that would be required for the entire name space. In addition, the code tables are smaller than in entirely known name spaces which requires less storage space in the codec and enables a faster encoding and decoding.

  • Patent number: 7982799
    Abstract: The invention relates to interpolation of an image information value for a pixel of an interline. The method comprises selecting, from a number of image directions, to each of which a direction quality value is assigned, a direction of interpolation by comparing these direction quality values. The image information value being interpolated is determined in dependence on image information values assigned to pixels lying adjacent to the pixel being interpolated in the direction of interpolation. To ascertain a direction quality value for an image direction a pixel group having at least two pixels is selected; a single direction quality value for each pixel of the pixel group is determined, the single direction quality value being dependent on image information values assigned to image regions lying adjacent to the particular pixel of the group in the image direction; and a direction quality value is created as a function of the single direction quality values of the pixel group.

  • Patent number: 7797346
    Abstract: A method is provided for encoding string-based data types, which have, for example, a tree-type structure, in such a way that signal bits (flags) for optional sections and/or for length information concerning the codes that are of variable length are placed in a defined sequence at the beginning of the created bitstream, thus accelerating the search for data via a sorting process and bit mask queries. A more efficient encoding is also provided of the #position field by, among other things, the assignment of code fragments for each group of regular expressions.

  • Patent number: 7707154
    Abstract: Methods and devices are provided for encoding/decoding structured documents, particularly XML documents, wherein a bit stream or part of a bit stream is produced from a schema as a function of a metaschema with the aid of an encoding method. Under an exemplary embodiment, at least one of the following optimization processes is carried out: separation of anonymous types from element declarations and attribute declarations and encoding as own type, the type definition thereof being instantiated in the schema definition as a top level element; normalization of the syntax trees on the encoder side; replacement of the character strings of type names; and transmission of information for the inheritance tree. The decoding takes such optimization processes into account and conversely produces a schema from the bit stream.

  • Patent number: 7233953
    Abstract: A method is provided wherein two different schema branch codes are used, whereby one of the two is utilized far more frequently and, as a consequence, effects a compression. The schema branch code and position code are combined, and the bit length for the schema branch code is transmitted therewith. This results in simplifying the search function in such a manner that the first part, alone, specifies the type of the referenced element and that an improvement in the extensibility is achieved based on a schema version number to be transmitted and on firmly prescribed extension strategies that are also familiar to the decoder.

  • Patent number: 7064793
    Abstract: To determine the noise contained in a picture, it is proposed first to determine homogeneous picture regions of the picture (100-102) and then to measure the high-frequency signal component in these homogeneous picture regions (BR). The measurement of the high-frequency signal components is here averaged over many measurement points, i.e. over many homogenous picture regions (BR), and is processed into a noise figure (NOISE_SUM) (103-104). In this way, the quality of the picture can be measured directly in the picture content.
