Abstract: The method comprising a temporal analysis implementing a motion compensated temporal filtering, said filtering comprising, to get a high frequency band picture H at a temporal level l, a predict step implementing high pass filtering of pictures L of lower temporal level, and, to get a low frequency band picture L at a temporal level l, an update step implementing low pass filtering of pictures H of same level and/or of pictures L of lower temporal level, also comprises, at least for a temporal level, a predict step which carries out a long filtering and an update step which carries out a short filtering. Applications relate to video compression for transmission or storage of data.
