| 中文摘要: |
| 基于 Shannon 信息论中有关信息量及信息熵的基本概念,通过对实际单色加网印刷图像的测试、计算和分析,获得了印刷图像的零阶、一阶、二阶信息熵。 这一分析方法及结果,对认识印刷过程图像信息传递特性具有重要意义。 |
| 英文摘要: |
| Based on the basic concepts of information-quantity and information-entropy in the theory of Shannon, tests of monochromatic screened printed images were carried out. After computing and analysis, the information quantity and information entropy of zero to second order were obtained. The analysis method and result are significant for the knowledge of information transmission characteristic of printing process. |
