虽然在某些情况下存在有效的字符识别方法,例如从印刷或手写文档中提取的字符,但这些方法在使用从自然图像中提取的字符进行测试时表现不佳。在这项工作中,我们介绍了面向基本图像特征(oBIFs),基于局部对称性和方向的系统,并演示了如何将它们用于自然图像字符识别的多尺度系统。当使用两个最常见的数据集进行测试时,性能最好的系统比以前的方法高出8.1%和1.2%。
Whilst effective methods exist for character recognition in certain contexts, such as characters taken from printed or handwritten documents, these methods have not performed well when tested with characters taken from natural images. In this work we introduce oriented Basic Image Features (oBIFs), a system based upon local symmetry and orientation, and demonstrate how they can be used within a mutliscale system for natural image character recognition. The best performing system outperforms previous methods by 8.1% and 1.2% when tested with the two most common datasets.
