摘要
在对动态仪表的数显数字字符图像识别中,将细化后的字符图像看作是一幅连通图,选择闭合曲线作为其整体特征,将笔画端点所处字符图像中子区域的位置做为主要的细节特征,对字符进行识别。试验结果表明该方案是可行的和有效的。
A thinned image is viewed as a graph.In the procession of image recognition of numeral instrument dynamic displayed, this paper selects closed curves as integrate features of those character images,makes the sub region where the end of last drawing of numbers locate of the character images as the major specific features,and then recognizes the character of numeral instrument dynamic displayed.The experiment results shows that the proposed approach is practical and effective.
