Abstract: Current deblocking filters are using the same filters with the same filtering strength irrespective of the block size and the size of the transform used. However, in the new video coding standards such as emerging HEVC the PU sizes can vary from 4 to 64 and the TU sizes can vary from 4 to 32. Therefore, filtering the same amount of pixels (e.g. two or three) from the block boundary for the block of size 4 can be excessive, while for the block size 32 it may not be enough, with the result that the boundary between two blocks is still visible. Hence, there is a need for an efficient deblocking filter control that can be used to reduce blocking artifacts at block boundaries and that does not have the above mentioned drawbacks. It is a general objective to provide an efficient deblocking filter control. Thus, the objective is solved by applying different filters for different block sizes such as CU, PU or/and TU sizes.
