Abstract: An image decoding method based on a low-complexity transformation is provided. The method comprises: executing a transformation with respect to a residual block based on a first transformation kernel, and executing a transformation with respect to the transformed residual block based on a second transformation kernel having low-complexity, wherein the first transformation kernel is derived based on a prediction block or an encoding unit block.

Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.

Abstract: A method for represents the surroundings of a vehicle with at least two levels of resolution in a surroundings model, preferably for a vehicle having a sensor system for monitoring the surroundings and at least one driver assistance system. The surroundings model preferably represents a probability grid having a plurality of grid cells. Data from at least two grid cells at a higher level of resolution are combined and stored in a grid cell at a lower level of resolution.
Abstract: A method of creating a variable-shaped block in a target image includes generating an initial pattern of target blocks, identifying allowable combinations of target blocks, calculating a combination value for each allowable combination, using the combination value to select one of the allowable combinations, and performing the selected allowable combination to create a variable-shaped block.
