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.

Abstract
A method generates a synthetic textured data signal by first acquiring a time-invariant input textured data signal. The input textured data signal is sampled to construct an observation matrix. The observation matrix is eigen-coding and factoring to identify a linear dynamic system modeling the input textured data signal. Then, the linear dynamic system can be run forward from an initial state using a quadratic regulator and a random noise signal to generate the synthetic textured data signal.
