摘要： The present invention relates to a method and a device for choosing a mode of coding from among a plurality of modes of coding for a subset of blocks included in a set of blocks. An energy function over the set of blocks for each of the modes of coding is calculated and calculation elements of the energy function are stored for at least the subset of blocks. A first mode of coding, minimizing the energy function over the set of blocks is chosen. The energy function over the subset of blocks for each of the modes of coding is thereafter calculated by using the calculation elements stored for the subset of blocks and by said subset, of a cost of coding for the modes of coding distinct from the first mode of coding. The choice of a mode of coding minimizing the energy function over the subset is then effected.

摘要： The invention is related to a method for determining a filter for interpolating one or more pixels comprised in a frame. The proposed method comprises the step of determining the filter based on other pixels in the remainder of the frame wherein a motion vector associated with said pixels has at least one motion parameter in common with another motion vector associated with said other pixels and the filter is determined such that a quality of an interpolation of said other pixels, said interpolation being determined by help of said determined filter, reaches or exceeds the quality of any other interpolation of said other pixels determinable by help of one of different filter candidates comprised in a filter candidate set. In determining the filter solely on different other pixels of the same frame, said method for determining a filter for interpolation allows for realization of a single pass encoding framework.
