Patent ID: 7643034

Claim:
A method for synthesizing advecting texture on a surface, comprising: using a computing device having a processor to generate a synthesized texture image on the surface resembling a user given exemplar image; measuring a distortion of the synthesized texture image by measuring a Frobenius error norm of the synthesized texture image; and selectively regenerating the synthesized texture image based on the measured distortion to cause the synthesized texture to flow over the surface while preserving an appearance similar to the exemplar: wherein the Frobenius error norm is given by: ξ=∥ J S −J∥ 2 , where ξ is the Frobenius norm, J is a desired anisometric Jacobian, J S is a Jacobian of a current synthesized texture, S, given by J S =(ddx(S) ddy(S)), where (ddx(S)) is an estimate of a derivative of synthesized coordinates along an x-axis, and (ddy(S)) is an estimate of a derivative of the synthesized coordinates along a y-axis.
