Abstract: A method of signal sample interpolation utilizing a second order curve utilizing a linear interpolator to select a mid-point between respective input samples, eliminating phase error and spatial variation, utilizing the interpolated points as reference points for a quadratic interpolation wherein the space between the reference points is one half the distance between respective signal sample points, and thirdly combining the operations of linear interpolation and quadratic interpolation for simultaneous execution. More particularly, the quadratic interpolation is reformed based on the output of the linear interpolation.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for computing motion vectors in a digital video sequence are disclosed. A recursive hierarchical method is used to determine a motion vector by using multiple resolution levels of the image frames. A best motion vector is first determined for the lowest resolution level. The best motion vector is propagated to a higher resolution level, where some adjustments are made and a new best motion vector is determined. The new best motion vector is propagated to yet another higher resolution level, where more adjustments are made and another new best motion vector is determined. This process is repeated until the highest, original, resolution level has been reached and a best motion vector has been identified. The identified best motion vector at the original resolution level is used for performing motion compensation.
