摘要

提出了一种基于结构构建范式和二维语法的离线数学公式识别方法。一般来说，这种方法可以成功地用于分析包含具有丰富结构关系的对象的图像。结构构造的一个重要优点是将图像中的符号分割及其结构分析视为一个相互交织的过程。这允许系统避免通常在分割阶段出现的错误。我们已经开发并测试了一项试点研究，证明该方法在计算上是有效的，实用的，并且能够处理噪声。

Mathematical Formulae Recognition Using 2D Grammars

We present a method for off-line mathematical formulae recognition based on the structural construction paradigm and two-dimensional grammars. In general, this approach can be successfully used in the analysis of images containing objects that exhibit rich structural relations. An important benefit of the structural construction is in treating the symbol segmentation in the image and its structural analysis as a single intertwined process. This allows the system to avoid errors usually appearing during the segmentation phase. We have developed and tested a pilot study proving that the method is computationally efficient, practical and able to cope with noise.
