Evaluation Structure and Algorithm for Printing Color Quality
-
摘要: 建立了3个层次的色彩质量评价体系,第1层次是对各墨区的各颜色分别进行评价;第2层次是对各墨区的色彩质量进行综合评价;第3层次是对整幅画面的色彩质量进行评价.对各个层次的评价算法进行了研究,其中第1层次的评价采用模糊层次综合评判法,建立了2级递阶层次结构,用灰关联分析法确定各因素间的相对重要程度,然后用层次分析法确定各因素的权重,最后用最大隶属度法确定评价结果;第2层次的评价采用加权算术平均法和模糊综合评判法;第3层次的评价采用加权算术平均法.算例表明,该评价体系结构及算法能对印刷色彩质量进行客观而准确的评价.Abstract: Three-level evaluation structure for color quality is established.The first level is to evaluate each color of each ink zone;the second level is to evaluate the color quality of each ink zone;and the third level is to evaluate the color quality of the whole image.The evaluation algorithm for each level is studied.The evaluation of the first level uses the fuzzy hierarchy comprehensive evaluation method,the relative importance of each factor is determined by the grey relevancy method,then the weight of each factor is determined by the analytic hierarchy process,and the evaluation result is finally determined by the max membership method.The evaluation of the second level uses the integration of the weighted arithmetic average method and fuzzy comprehensive evaluation method.The evaluation of the third level uses the weighted arithmetic average method.The example indicates that the evaluation structure and the algorithm can objectively and correctly evaluate the printing color quality.
