Research on the Spectral Reflectance Model based on Optical Dot Gain

彩色半色调印刷品色彩预测模型是彩色图像复制领域内的关键技术,为建立更加准确的色彩预测模型,本文分析了光子在油墨中的传输,将光子传播类型分成四类并分别进行建模,最后提出了基于马尔可夫链理论的光谱反射率数学模型,并通过实验证明新模型具有更好的色彩预测精度。

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 pa- per 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.
