The formation of color components of face images is a complex
computational task, since for each pixel of a surface it is necessary to calculate the
color intensity, for which it is necessary to determine the unit vectors to the light source
and normal to the surface. Therefore, the urgent task is to simplify the coloring
procedure without losing the realism of the final image. It is suggested to use seconddegree
and third-degree polynomials to adapt to painting, depending on the surface
curvature. For the third degree polynomial, an approximation formula is obtained to
determine the diffuse and specular color components. The hardware for determining
the coefficients and the approximation polynomial is proposed.
