摘要
纸页匀度是评价纸张质量的一个重要指标,也是纸页的最重要性能之一。文章提出了一种用MATLAB软件来分析纸页匀度的方法。通过采集的纸页匀度图像,利用MATLAB软件进行图像处理,获取纸页匀度的灰度直方图和均方差,通过分析这些数据比较不同纸样的匀度情况。灰度直方图可以直观定性地判断出纸页匀度的好坏,均方差则是通过数据的分析比较,得出纸页匀度好坏的定量结果。
Paper sheet uniformity is a very important indicator in evaluating paper quality. A new method to test paper uniformity using MATLAB software is introduced in this paper. The images of paper sheet uniformity are collected,and treating images with MATLAB software can obtain the gray histogram distribution,mean-square deviation of the images. Through these data to compare different paper sheet uniformity,the gray histogram distribution indicates the quality of the paper sheet uniformity,while the quantitative analysis can be evaluated by the mean square deviation.
