摘要/Abstract

摘要： 随着图形图像处理技术的迅速发展,图像增强及识别方法已广泛应用于各行各业。在此基础上,文字识别技术也取得了极大的进步。针对水族文字笔触随意、字形多变、噪声较多等问题,文中提出了一种改进的图像增强及识别方法。通过中值滤波算法降低图像噪声,利用直方图均衡化方法增强图像对比度,再经过二值化处理提取图像中的目标轮廓,通过腐蚀膨胀处理细化和扩张背景,最后采用改进的文字提取算法凸显水族文字,采用Sobel算子提取水族文字边缘,并对其进行仿真对比实验。实验结果表明,该方法有效地降低了图像噪声,准确地提取出了水族文字轮廓,可以应用于民族文字提取及识别、文物修复、图像增强等领域,对保护民族文物遗产、弘扬少数民族传统文化具有重要意义。

关键词: 水族文字识别, 图像识别, 图像增强, 文字提取, 直方图均衡化

Abstract: With the rapid development of graphic image processing technology,image enhancement and recognition methods have been widely used in various industries.On this basis,text recognition technology has also made great progress.Aiming at the problems of shui text random brush strokes,variable fonts and more noise,this paper proposed an improved image enhancement and recognition method.The median filtering algorithm is used to reduce image noise,and the histogram equalization method is used to enhance image contrast.The binarization process is executed to extract the target text in the image,and the corrosion expansion process is executed to refine and expand the background.Finally,the improved text extraction algorithm is used to highlight the outline of the shui text,and the Sobel operator is used to extract the edge of the shui text.The simulation contrast experiment was carried out.The experimental results show that the method effectively reduces image noise,and accurately extracts shui characters.The method can be used in the fields of national character extraction and recognition,cultural relics restoration,image enhancement,etc.It is of great significance for protecting the heritage of ethnic cultural relics and carrying forward the traditional culture of ethnic minorities.

Key words: Histogram equalization, Image enhancement, Image recognition, Shui-character recognition, Text extraction
