1. A method for generating a synthetic textured data signal, comprising:

  • acquiring a time-invariant input textured data signal including a sequence of frames;

    sampling the input textured data signal to construct an observation matrix;

    eigen-coding and factoring the observation matrix to identify a linear dynamic system modeling the input textured data signal; and

    running the linear dynamic system forward from an initial state using a quadratic regulator and a random noise signal to generate the synthetic textured data signal, further comprising;

    selecting a set of keyframes from the sequence, each keyframe having an associated state at a particular time; and

    running the linear dynamic system through the keyframes to pass through predetermined states at predetermined times.
