1. A method for interpolating an image between first and second adjacent images, comprising: estimating a block-based forward motion vector and a block-based backward motion vector between the first and second adjacent images; selecting a forward motion vector for each pixel in the image based on the block-based forward motion vector and a forward error function; selecting a backward motion vector for each pixel in the image based on the block-based backward motion vector and a backward error function; interpolating a first image from the selected backward motion vectors, the selected forward motion vectors, a block-based forward estimation error, and a block-based backward estimation error; interpolating a second image from the first image based on forward and backward weighted errors of the selected forward motion vector and the selected backward motion vector; and determining the image from the second image.
