)

Add a motion vector to the set of motion vector lists, making sure it's not a duplicate.

ValueType GetVar ( const std::vector< MVector > & pred_list,

const MVector & mv

)

Return the variation between a motion vector and a list of motion vectos, computed as the sum of absolute differences between the components of the vector and the median vector produced by the list of vectors

ValueType GetVar ( const MVector & mv1,

const MVector & mv2

)

Return the variation between two motion vectors, computed as the sum of absolute differences of their components.
