1. A method for generating motion vectors, the method comprising:

  • identifying a motion vector of an image at a first resolution;

    using the identified motion vector to generate a first test vector and a second test vector for the image at a second resolution, the second resolution of higher resolution than the first resolution;

    determining one or more camera model parameters at the second resolution of the image based on the first test vector, the second test vector, and known position locations in the image; and

    generating a first motion vector and a second motion vector for the known position locations in the image at the second resolution based on the one or more camera model parameters.
