Abstract: In one embodiment, a method receives a video bitstream corresponding to compressed video, wherein Filter Unit (FU) based in-loop filtering is allowed in a reconstruction loop associated with the compressed video. The method then derives reconstructed video from the video bitstream, wherein the reconstructed video is partitioned into FUs and derives a merge flag from the video bitstream for each of the FUs, wherein the merge flag indicates whether said each of the FUs is merged with a neighboring FU. The method further receives a merge index from the video bitstream if the merge flag indicates that said each of the FUs is merged, and receives the filter parameters from the video bitstream if the merge flag indicates that said each of the FUs is not merged. Finally, the method applies the in-loop filtering to said each of the FUs using the filter parameters.

Abstract: The invention relates to an assisting apparatus for assisting in performing brachytherapy. The position of an introduction element (17) like a catheter is tracked particularly by using electromagnetic tracking, while a group of seeds is introduced into a living object (2). This provides a rough knowledge about the position of the seeds within the object. An ultrasound image showing the group is generated depending on the tracked position of the introduction element and, thus, depending on the rough knowledge about the position of the seeds, in order to optimize the ultrasound visualization with respect to showing the introduced seeds. Based on this optimized ultrasound visualization the position of a seed of the group is determined, thereby allowing for an improved determination of seed positions and correspondingly for an improved brachytherapy performed based on the determined positions.
