Abstract: An image processing unit for computing a sequence of output images on basis of a sequence of input images, comprises: a motion estimation unit for computing a motion vector field on basis of the input images; a quality measurement unit for computing a value of a quality measure for the motion vector field; an interpolation unit for computing the output images by means of interpolation of pixel values of the input images, on basis of the motion vector field; and control means to control the interpolation unit on basis of the quality measure. The quality measurement unit is arranged to compute the value of the quality measure on basis of a maximum difference between neighboring motion vectors. If the value of the quality measure is lower than a predetermined threshold, then a motion compensated interpolation is performed, else a non-motion compensated interpolation is performed.

Abstract: A method for refining aqueous suspended fibers, the fibers being paper fibers or pulp fibers including the steps of leading, pressing, forming, temporarily attaching, supplying and discharging. The leading step includes leading the aqueous suspended fibers through at least one refining zone which is located between an inside wall of a rotating refiner drum and at least one refiner roll, the refiner roll rotating in association with the refiner drum. The pressing step includes pressing the refiner roll and the refiner drum against each other thereby causing a mechanical refining force to be transferred to the fibers so that strength properties of paper produced therefrom are altered. The forming step includes forming a fibrous stock layer on the inside wall of the rotating refiner by the aqueous suspended paper fibers. The temporarily attaching step includes temporarily attaching the fibrous stock layer to the inside wall due to rotation.
