A method for generating comfort noise is provided. The method includes providing a first set of background noise parameters Nfor at least one audio signal in a first spatial audio coding mode and a second set of background noise parameters Nfor the at least one audio signal in a second spatial audio coding mode. The first spatial audio coding mode is used for active segments; the second spatial audio coding mode is used for inactive segments. The method further includes adapting the first set of background noise parameters Nto the second spatial audio coding mode, thereby providing a first set of adapted background noise parameters {circumflex over (N)}. The method further includes generating comfort noise parameters by combining {circumflex over (N)}and Nover a transition period. The method further includes generating comfort noise based on the comfort noise parameters.

Comfort noise generation for multi-mode spatial audio coding

The invention relates to a computer implemented method for associating objects in a video comprising subsequent frames, the method comprising obtaining first object proposal region information of a previous frame, determining second object proposal region information of a current frame, wherein the first and second object proposal region information are at least indicative of an appearance measure, a spatial location and a detection probability of each object proposal region of the respective frame, associating objects in the video by at least associating a first set of object proposal regions of the previous frame to a second set of object proposal regions of the current frame, wherein the object proposal regions are associated using distance measures calculated based on the appearance measures, the spatial locations and the detection probabilities.
