Abstract
The invention proposes a motion compensated video interpolation that is not sensitive to the errors in the motion estimation vectors. The invention proposes a motion compensated video interpolation method in which the interpolation step varies according to the amplitude and/or a reliability index of the estimated motion vector for the considered pixel. The number of pixels to be taken into account for interpolation and the weighting factors associated with these pixels are made to vary according to the amplitude and/or reliability index of the estimated motion vector.
