Abstract: The invention relates to a computer-implemented method for estimating the movement of an image position of an image feature between a first image and a second image. The method includes: Determining a set of image windows in the first image, each image window having the image feature; Identifying at least a portion of the set of image windows in the second image; For the portion of the set of image windows, evaluating the quality of an assignment of each image window in the first image to the given image window in the second image, and selecting one of the image windows on the basis of the evaluation; and estimating the movement of the image position of the image feature using the selected image window. In the second image, the selected window is identified by iteration over more resolutions than the windows of the at least one portion.

Abstract: The present disclosure relates to methods and devices for creating a bit rate ladder for encoding representations of a video section. Creating includes generating a set of reference points, where a reference point indicates a quality of a representation based on the bit rate and the resolution. A subset of reference points is selected to create the bit rate ladder while taking quality requirements into account.

Abstract: The present invention relates to methods and devices for determining a set of quality levels and to encoding representations of a video section. Determining a set of quality levels for the respective associated representations of a video section takes special consideration of the resulting subjective quality during creation. This is described primarily by quality-based parameters. They are the highest and lowest quality and the quality level among the individual representations.
