FIELD: physics; image processing. ^ SUBSTANCE: invention relates to video compression systems, particularly to a filter for eliminating modularity. A video encoder is proposed, which is based on several layers, which uses the filter for eliminating modularity, containing: apparatus for encoding the input frame; apparatus for decoding the said encoded frame; apparatus for selecting filtration intensity for eliminating modularity in accordance with whether a unit, included in the decoded frame, was coded using internal BL mode, where if, at least the current unit and the neighbouring unit were encoded using a mode other than internal BL mode, the given filtration intensity is selected with respect to the boundary between the current unit and the neighbouring unit; and if the current unit and the neighbouring unit were encoded using internal BL mode, filtration intensity, which is lower than filtration intensity, selected with respect to the boundary, is selected; and filtering apparatus for eliminating modularity with respect to the boundary between a unit and a neighbouring unit in accordance with the selected filtration intensity for eliminating modularity. ^ EFFECT: more accurate selection of filtration intensity for eliminating modularity taking into account internal base layer (BL) mode. ^ 7 cl, 19 dwg |
