Abstract:

A new scanner calibration algorithm on the basis of 3D_Lut is presented,by which high-accuracy color calibration of equipments is achieved according to the arbitrary and irregular color sample patches of scanners.To solve the problem of operation complexity due to the large quantity of samples,a new method of adaptive tabulation and interpolation is proposed.This algorithm has the advantages over the traditional algorithm of scanner calibration of high accuracy and good real-timeness and that it can be used for color calibration of various equipments.
