Abstract:
A method for estimating motion of a motion picture, the motion picture comprising a plurality of images, the method comprising the steps of:estimating from a k-th image and a (k+1)-th image a motion parameter corresponding to each pixel of the k-th image to generate a first-order motion distribution image corresponding to the k-th image, the first-order motion distribution image corresponding to the k-th image represented by the motion parameters corresponding to the pixels of the k-th image;estimating from at least the (k+1)-th image a motion parameter corresponding to each pixel of the (k+1)-th image to generate a first-order motion distribution image corresponding to the (k+1)-th image, the first-order motion distribution image corresponding to the (k+1)-th image represented by the motion parameters corresponding to the pixels of the (k+1)-th image;updating the first-order motion distribution image corresponding to the (k+1)-th image to generate a second-order motion distribution image corresponding to the (k+1)-th image;predicting, from the image second-order motion distribution image corresponding to the (k+1)-th image, a third-order motion distribution image corresponding to the (k+2)-th image; andinterpolating the third-order motion distribution image corresponding to the (k+2)-th image to generate a fourth-order motion distribution image corresponding to the (k+2)-th image, where k is an integer, andwherein the step of updating updates the first-order motion image distribution image corresponding to the (k+1)-th image using a higher than first-order motion distribution image generated from the k-th image.
