The theory of multicolor codes of pseudo-random array, the invariance of cross-ratio in algebraic projective geometry and the calibration model of projector which is regarded as a reverse camera are presented, and detailed steps to be taken for calibrating the projector are described.

A pattern with multicolor codes and a projector constitutes a new projection system through which the pattern of multicolor codes is illuminated by the lighting system and projected onto the 3D scene.

Search time was tested as a index for evaluating visual performance of color coding for characters and parametric effects of foreground color, background color, character size and illuminant condition on the visual performance in synthesized information displays.

Kernelization and color coding are important techniques to design parameterized algorithms.

By using digital image processing technique a new color encoding method for photomechanics fringes is presented.

The Evolution and Application of Color-coding;

Thus, color-coding is a fundamental problem, and itsimprovement will lead to a series of breakthroughs in many other prob-lems.
