The present invention relates to a method for interpolating a subpixel at an interpolation position, which is situated in the chronological order between two source frames. Thereby the calculation of the interpolated subpixel's value is based on the value of the pixels of the two source frames and additional weighting coefficients, which are based on the motion vectors correlating the two source frames.

The present invention relates to a method for classifying digital image data (ID) which solves the problem that images (I) having image areas with artificial text overlay have to be detected and classified in video signals in a reliable manner. Therefore, a robust detection in the presence of additive noise is proposed which can be invariant with respect to interlaced or progressive modes of video sequences.
