Abstract: Some examples may relate to an object-recognition system. The object-recognition system may generate an object identifier when an object having detectable elements in a predetermined spatial pattern is in proximity to a capacitive sensor. The object-recognition system may include a capacitive sensor and a reader to capture channel-capacitance measurements at least partially responsive to the capacitive sensor in proximity of the detectable elements. The object-recognition system may include a recognizer to generate an object identifier at least partially responsive the captured channel-capacitance measurements.

Abstract: In a motion vector estimation method, a block-based motion vector estimation process (BME) that involves comparing a plurality of candidate vectors is carried out to determine block-based motion vectors, at least a most frequently occurring block-based motion vector (MFMV) is determined, a global motion vector estimation process (GME) using at least the most frequently occurring block-based motion vector (MFMV) is carried out to obtain a global motion vector (GMV), and the global motion vector (GMV) is applied as a candidate vector to the block-based motion vector estimation process (BME).

Abstract: An advanced video compression coding system which employs variable block size transforms to improve the compression efficiency for transmission of video pictures. A picture block segmentation map is transmitted as a one-dimensional series of block-size codes by scanning the segmentation map in accordance with a predetermined scanning pattern and on the basis of block size. A block-size code is skipped when the scanning pattern intersects a block which has already been scanned earlier. The series of block-size codes is then run-length and Huffman-coded before being transmitted.

Abstract: Device for splitting an interlaced television frame into a vertical low-frequency spatial signal and a vertical high-frequency motion auxiliary signal. In a forward play mode the two signals are added together. In a reverse play mode, in which the frames are supplied in the reverse order, the motion auxiliary signal is subtracted from the spatial signal.

Abstract: Device for splitting a digital interlaced television signal into components in which interlaced frames are applied to a vertical low-pass filter (6). To prevent motion artefacts in the spatial signal thus obtained, the interlaced frame is also applied to a vertical high-pass filter (8). This vertical high-pass filter supplies a motion auxiliary signal which may have a small vertical bandwidth. When combining the spatial signal and the motion auxiliary signal, noticeable motion artefacts do not occur in the interlaced frame. The device may be used for deriving a standard television signal from a high-definition television (HDTV) signal and for compatible transmission of HDTV signals.
