基于特征提取的快速图书损坏鉴评方法研究

Research on Fast Book Damage Evaluation Method Based on Feature Extraction

文章针对图书损坏现象,提出一种基于特征提取的快速图书损坏鉴评方法。对出借和归还时图书的正反侧三面图像进行差异度检测,评判图书损坏是否超过损坏阈值;找到差异度位置区域,并利用一种新的有监督的分析方法对该区域进行特征提取,继而分类匹配,判定损坏类型和损坏程度,提示图书馆工作人员及时进行图书修复,督促读者爱护书籍,养成良好的阅读习惯。同时,文章采集某高校图书馆内的1000本纸质藏书,将所提方法与传统的特征提取方法进行对比实验,结果表明文章所提方法的识别精度更高。

In view of the phenomenon of book damage,this paper proposes a fast book damage evaluation method based on feature extraction.This method detects the difference degree of the front,back and side images of books during lending and returning,and evaluates whether the damage of the book exceeds the damage threshold;finds the location area of the difference degree,and uses a new supervised analysis method to extract features from this area,and then classifies and matches to determine the type and degree of damage,prompting the library staff to repair books in time,urging readers to take good care of books and cultivate good reading habits.At the same time,this paper collects 1000 books from a university library,and compares the proposed method with the traditional feature extraction methods.The results show that the proposed method has higher recognition accuracy.
