Velocity estimation from imagery using symmetric displaced frame difference equation

A method and apparatus for processing an image sequence described herein that provides a symmetric displaced frame difference equation. Next, an input image sequence can be received that includes a pair of image frames individually including multidimensional image data corresponding to a plurality of pixel locations at different times. Finally, using at least one processor, the symmetric displaced frame difference equation can be solved using an iteration equation and the image data of the pair of image frames to determine a displacement field describing displacement vectors at half of the total displacement vector.
