| 摘 要： | 数字图像的质量直接决定着印刷品的质量,数字图像的清晰度是判断数字图像质量的重要指标。建立印前数字图像清晰度评价标准对于印刷业有着广泛的意义。印前数字图像清晰度可以从有参考和无参考两个方面进行评测。有参考评测主要根据印刷图像所需要的分辨率要求确定当前图像是否符合印刷要求。无参考评测可以利用基于焦点窗口的清晰度评价方法,检测出图像的不同区域清晰度,并以此作为印刷图像清晰度的参考值。以上两种方法在实际应用中都取得了良好的效果。

| Abstract: | The quality of the digital image directly determines the print quality,the clarity of digital images is an important indicator to judge the quality of digital images.The evaluation criteria of prepress digital image clarity has a broad meaning for the printing industry.Prepress digital image clarity from the reference and no reference for evaluation.Reference evaluation mainly based on the printing image resolution requirements to determine whether the current image to meet the printing requirements.No reference evaluation can take advantage of the different regions of the evaluation method based on the clarity of focus window,to detect image clarity and as a reference value of the printed image.In practical application,the above two methods have achieved good results. |
