  • Method for coding and decoding a digitalized image
    Patent number: 7173968
    Abstract: A method and an arrangement in which a digitized image with picture elements is allocated to a number of image segments. The image segments, preferably image blocks, are spread such that interspaces remain between the image blocks to be encoded. The interspaces are interpolated after decoding.
    Type: Grant

    Date of Patent: February 6, 2007
    Assignee: Siemens Aktiengesellschaft
    Inventors: Robert Kutka, Stathis Panis
  • Method and arrangement for vector quantization and for inverse vector quantization of a digitized image
    Patent number: 6360020
    Abstract: In a vector quantization of a digitized image, image regions (QB) to be quantized are selected smaller than, for example, image blocks (BB) of an image (B). In the reconstruction, image points (NBP) that are not located in an image region (QB) to be quantized are interpolated and/or extrapolated.

  • Method for computer-supported motion estimation for picture elements of chronologically following images of a video sequence
    Patent number: 5973754
    Abstract: In a method for computer-supported motion estimation for picture elements of chronologically successive images of a video sequence, a motion estimation is implemented with using a known dynamic programming (DP) method. A further dimension is added to the optimization space of the DP algorithm. As a result, the motion of objects is recognized in all directions and an incorrect classification of picture elements as an occlusion, which could not be prevented in known methods, is thus avoided.

  • Method of computer assisted motion estimation for picture elements of chronologically successive images of a video sequence
    Patent number: 5726713
    Abstract: A motion estimation is implemented using a known dynamic programming method (DP method). A further dimension is thereby added to the optimization space of the DP algorithm. As a result thereof, the motion of objects is recognized in all directions and an incorrect classification of picture elements as occlusion, which could not be prevented in known methods, is thus avoided.
