摘要
 本課題利用計算機圖像處理技術來研究紙頁勻度的特征，并進一步構建了紙頁勻度測試系統。利用多種圖像處理方法，包括均方差法和灰度直方圖法等來認識和表征紙頁勻度。
 紙頁勻度不好不但影響到紙的外觀，而且影響到幾乎所有的物理性能，光學性能和印刷性能。一套準確表征紙頁勻度的檢測系統對于正確認識紙頁勻度的理論和紙頁勻度的標準化工作有一定的實際意義。通過采集廠家生產的紙樣，計算機視覺技術可以很好地應用于紙頁性能分析及其相互間的相關分析。利用計算機視覺系統分析采集到的透射光信號，并據此分析紙頁的勻度情況。
關鍵詞：計算機視覺；紙頁勻度；圖象分析；透射光信號

ABSTRACT
 The characteristics of paper formation is studied in this paper by using image processing techniques , and paper formation test system is established. A variety of image processing methods are used, including variance and gray histogram method to understand and Characterization paper formation.
 Paper information of the poor will affects not only the appearance of paper, but also almost all of the physical properties and optical properties and print properties. A precise characterization of paper formation detection system s a high significance for a correct understanding of paper formation and its standardization is a high significance. By collecting various products manufacturers ,the Computer vision technology can be applied to all kinds of good pages performance analysis and their inter-correlation analysis. The optical signal of transmission is captured by using computer analysis of visual processing, and it is used to analyse paper information.
