Abstract: The invention relates to an image processing device (1) for finding corresponding first and second regions in two image data sets of an object. In a first image data set a source line and in a second image data set a corresponding target line are determined depending on reference regions detectable in both image data sets. A first region in the first image data set is projected onto the source line, thereby dividing the source line into two source sub-lines and defining a source ratio as the ratio of the length of one of the source sub-lines to the length of the entire source line. A second region in the second image data set is then determined such that a projection of the second region onto the target line leads to a corresponding target ratio which is similar to the source ratio.

Abstract: A two-stage signaling concept for a datastream to be transmitted from a transmitter to a receiver is proposed. At the transmitter side, a plurality of frame headers are generated, each frame header including data transmission parameters for payload data. A super-frame header for a super-frame is generated. The super-frame includes a plurality of frames, each frame including one of the frame headers and payload data. The super-frame header indicates a set of super-frame-constant frame header transmission parameters for the frame headers of the plurality of frames of the super-frame. A receiver evaluates the super-frame header of to obtain the super-frame-constant frame header transmission parameters, which are then used to evaluate the plurality of frame headers PLH to retrieve the data transmission parameters. The proposed concept provides added flexibility, less signaling overhead, and/or an option of improved receiver performance at low SNR levels.

Abstract: The present invention describes a method and an arrangement for coding transform coefficients in picture and/or video coders and decoders and a corresponding computer program and a corresponding computer-readable storage medium, which can particularly be employed as a novel efficient method for binary-arithmetic coding transform coefficients in the field of video coding. For this, it is suggested that, for blocks of (video) pictures containing significant transform coefficients, coding of the transform coefficients takes place in such a way that, for each block in a scan process, the positions of significant transform coefficients in the block and subsequently, in a reverse scan order—starting from the last significant transform coefficient within the block—the values (levels) of the significant transform coefficients are determined and coded.

Abstract: A selected channel of a multi-channel signal which is represented by frames composed from sampling values having a high time resolution can be encoded with higher quality when a wave form parameter representation representing a wave form of an intermediate resolution representation of the selected channel is derived, the wave form parameter representation including a sequence of intermediate wave form parameters having a time resolution lower than the high time resolution of the sampling values and higher than a time resolution defined by a frame repetition rate. The wave form parameter representation with the intermediate resolution can be used to shape a reconstructed channel to retrieve a channel having a signal envelope close to that one of the selected original channel. The time scale on which the shaping is performed is shorter than the time scale of a framewise processing, thus enhancing the quality of the reconstructed channel.
