数字图像色彩评价方法的探讨

Study on the Method of Evaluating about Digital Image

对彩色数字图像和层次分析法建模理论做了大量调查、分析和研究 ,根据彩色数字图像复制处理过程中的颜色再现理论和原理 ,提出了评价数字图像色彩复制质量的指标体系 ,并参照国家或行业标准 ,给出了各指标的相对评判标准 ,利用层次分析法建立了数字图像色彩复制质量综合评价的数学模型 ,设计出一套色彩复制与处理的综合评价数学方法。最后 ,用VB基本实现了对彩色数字图像进行模拟评估的目标。

This paper makes a great investigations, analysis and researching on color digital images and the modeling theory of analytic hierarchy process.Based on the theory and principle of color reproducing in color digital images copy process,a index system evaluating the quality of digital images color reproducing is presented. Referring to the national or trade standard, a relative judge standard of qualitative and quantitative index is given. Using the analytic hierarchy process in mathematics, it establishes a mathematics modeling of quality synthetical evaluation of digital images color reproducing, and designs a set of mathematics methods of synthetical evaluating color copying and processing.Finally,using VB to design panel,it basically realizes the simulated evaluating color digital images in computer,gives a systematic and fixed quantity way for color's reproduce for color digital images.
