Abstract: The invention relates to a temperature distribution determination apparatus for determining a temperature distribution within an object (20), while an energy application element (2) applies energy to the object, especially while an ablation procedure for ablating a tumor within an organ is performed. A time-dependent first ultrasound signal is generated for an ultrasound measurement region within the object and a temperature distribution within the object is determined based on the generated time-dependent first ultrasound signal and based on a position of the energy application element (2) relative to the ultrasound measurement region tracked over time. This can ensure that always the correct position of the energy application element, which may be regarded as being a heat source, is considered, even if the energy application element moves, for instance, due to a movement of the object. This can lead to a more accurate determination of the temperature distribution.

An out-of-bounds node is a coding tree node with a block region across a current picture boundary. The video processing method or apparatus determines an inferred splitting type, applies the inferred splitting type to split the out-of-bounds node into child blocks, adaptively splits each child block into one or multiple leaf blocks, and encodes or decodes the leaf blocks in the out-of-bounds node inside the current picture. The inferred splitting type for partitioning out-of-bounds nodes in an inter slice, picture, or tile is the same as the inferred splitting type for partitioning out-of-bounds nodes in an intra slice, picture, or tile.

In another method, a target clipping value is always signaled at an encoder side or parsed at a decoder side even if the target clipping value is zero. In another method, the clipping values are encoded or decoded using a fixed-length code.
