用于数学公式的OCR库 [英] OCR lib for math formulas

问题描述

我需要一个开放的OCR库，该库能够扫描复杂的打印数学公式(例如，某些通过LaTeX生成的公式).我想得到一些类似LaTeX的输出(或者只是一些类似AST的数据).

I need an open OCR library which is able to scan complex printed math formulas (for example some formulas which were generated via LaTeX). I want to get some LaTeX-like output (or just some AST-like data).

已经有这样的东西了吗?还是当前的OCR技术只能解析面向行的文本?

Is there something like this already? Or are current OCR technics just able to parse line-oriented text?

(请注意，我还发布了有关Metaoptimize的问题，因为那里的某些人可能还有其他知识.)

(Note that I also posted this question on Metaoptimize because some people there might have additional knowledge.)

OpenAI还将该问题描述为 im2latex .

The problem was also described by OpenAI as im2latex.

推荐答案

SESHAT是用C ++编写的用于识别手写数学表达式的开源系统. SESHAT是瓦伦西亚大学(UniversitatPolitècnicadeValència)PRHLT研究中心的博士学位论文的一部分.

SESHAT is a open source system written in C++ for recognizing handwritten mathematical expressions. SESHAT was developed as part of a PhD thesis at the PRHLT research center at Universitat Politècnica de València.

Seshat是用于识别手写数学表达式的开源系统.给定一个以笔划序列表示的样本，解析器可以将其转换为LaTeX或其他格式，例如InkML或MathML.

Seshat is an open-source system for recognizing handwritten mathematical expressions. Given a sample represented as a sequence of strokes, the parser is able to convert it to LaTeX or other formats like InkML or MathML.
