Abstract
A method for motion estimation in video image data comprises a step of providing a block of pixels (B(F(t))) of a current image (F(t)) and a block of pixels (B(F(t−1))) of a previous image (F(t−1)) and a block of pixels (B(F(t−2))) of a pre-previous image (F(t−2)). A reconstructed block of pixels (B*(F(t), F(t−2),v)) is determined by combining the block of pixels of the previous image (B(F(t−1),v) and the block of pixels of the pre-previous image B(F(t−2),v)). A motion vector (v) of the block of pixels of the current image (B(F(t))) is evaluated by comparing the block of pixels of the current image (B(F(t))) with the reconstructed block of pixels (B*(F(t), F(t−2),v)).
