摘要
扫描仪作为印前系统采集图像信息最常用的设备之一,其成像质量直接影响图像的扫描与输出质量。在扫描成像过程中,存在许多不可抗性因素,造成扫描图像模糊、失真和存在噪声等问题。本研究提出了一种结合调制传递函数与平均结构相似度的扫描仪成像质量评价方法。实验中选定ISO 12233标版图像以及自然图像原稿作为测试对象,将高精度滚筒扫描仪作为参照比对的标准设备。实验结果表明,该评价方法对扫描仪成像质量的评价结果与人眼主观评价结果一致。
Scanner is one of the most commonly equipments used to collect image information in the prepress system.The imaging quality of the scanner directly affects the quality of scanning and outputing images.In the process of scanning imaging,there are many irresistible factors,leading to scanning images with fuzzy and non-uniformity.In this study,a scanner imaging assessment method based on MTF and MSSIM was proposed.In the experiment,the images in ISO 12233 standard and natural images were selected as test images,the drum scanner with high precision was taken as the standard equipment.The experimental results showed that the evaluation results with this method are consistent with human subjective evaluation.
