| Abstract: | The accurate spectral reflectance model of coloring halftone is the key technology in the image reproduction,In order to build a more accurate color predict model,this paper analyzes the propagation of photon in ink and paper layers,and then we divided the flux into four classes which are modeled separately.Finally,a spectral reflectance model of halftone image is obtained based on the Markov chain.The accuracy of the new model is proved by the experiment in the end. |
