Patent Images

1. One or more computer-readable storage media containing a program that is executable by a computer to estimate motion between two images, the program configured to perform the following actions:

  • determining locations of a plurality of distinct facial features in the two images;

    converting the determined locations into a set of physical face parameters based on a symmetry of the distinct facial features;

    calculating an estimation objective function comprising a set of terms to estimate;

    (a) each of the parameters, (b) a first transform corresponding to a first image of the two images, and (c) a second transform corresponding to a second image of the two images; and

    estimating motion between the two images based on the set of physical face parameters by multiplying each term of the estimation objective function by a weighted contribution factor based on the confidence of data corresponding to the estimation objective function.
