摘要：
A method of estimating a particular motion vector (DR(x, n+α)) for a particular pixel, having a particular spatial position and being located at a temporal position (n+α) intermediate a first image and a second image of a sequence of video images, on basis of a first motion vector field (D3(x, n−1)) being estimated for the first image and on basis of a second motion vector field (D3(x, n)) being estimated for the second image is disclosed. The method comprises: creating a set of motion vectors (Dp, Dn, Dc) by selecting a number of motion vectors from the first motion vector field (D3(x, n−1)) and second motion vector field (D3(x, n)), on basis of the particular spatial position of the particular pixel; and establishing the particular motion vector (DR(x,n+α)) by performing an order statistical operation on the set of motion vectors (Dp, Dn, Dc).
