Abstract
Multiscale coefficients for each input video frame are distributed into K>1 groups. A first group of coefficients provides a representation of the frame at a first resolution level. For each integer k (1<k≦K), a kgroup of coefficients and the representation of the frame at the (k−i)th resolution level determine a representation of the frame at a kresolution level. Directions of regularity (motion vectors) are associated with output pixels based on representations of successive input frames at one or more of the resolution levels. An interpolated pixel value is determined for the output pixel using each direction of regularity (motion vector) associated with this pixel by interpolating between pixel values from representations of successive input frames at one or more of the resolution levels. A direction of regularity (motion vector) is taken into account using representations of the successive frames of the input video sequence at one or more of the resolution levels depending on this direction of regularity (motion vector).
