ABSTRACT:
A processing of causing a face image of a person A as an object of encoding to be deformed in correspondence to expression and motion of a face image of a person B as a reference image. The expression change and the motion from the model wire-frame are treated as fitting information, and this fitting information is made WA1 with respect to a first image of an object for photographing, while is made Wb1 with respect to a second image of an object for photographing. For example, the fitting information from a model wire-frame W00 to an image A1 is Wa1, and the fitting information from the image A1 to the model wire-frame W00 is Wa1. Next, an image A2 into which the first image A1 is caused to be deformed by a texture Ta1 of the first image A1 and a wire-frame function Wb1 Wa1 is obtained through composition. Texture mapping of sticking the texture Ta1 in correspondence to each of small areas of this wire-frame is carried out, whereby the image A2 into which the image A1 is caused to be deformed similarly to an image B1 is obtained through composition.
