| 目的 针对印刷墨斑的评价和测量，构建基于小波细节能量的印刷墨斑评价方法及模型。方法 以铜版纸印刷品的印刷墨斑为例，利用图像小波去噪后的细节能量求和作为印刷墨斑的评价指标，与人眼视觉评价体系做相关性分析，对比两者的评价结果。结果 构建的小波细节能量墨斑模型比传统COV模型具有较高的精确度。传统模型的相关系数为0.2009，经小波细节能量处理后的相关系数最小为0.5256，相关系数得到明显提高。结论 小波细节能量模型能够作为一种有效的方法代替人眼视觉进行印刷墨斑的评价与分析。 |

| The work aims to establish the evaluation method and model of printing mottle based on wavelet detail energy regarding the evaluation and measurement of printing mottle. Taking the printing mottle of copperplate paper for example, the sum of detail energy of denoised image wavelet was used as the evaluation indicator of printing mottle and the correlation analysis was made with the human visual system. Then the evaluation results of the both were compared. The established mottle model of wavelet detail energy was more accurate than the traditional COV model. The correlation coefficient of the traditional model was 0.2009. The minimum correlation coefficient was 0.5256 and it was significantly improved after wavelet detail energy treatment. Taken together, wavelet detail energy model can be used as an effective method for the evaluation and analysis of printing mottle instead of human vision. |
