通过稀疏图分割实现非受控条件下的文本阅读顺序（英文版）

英文标题：Text Reading Order in Uncontrolled Conditions by Sparse Graph Segmentation中文摘要：本文提出了一种轻量、可扩展和通用的方法，通过运行在稀疏布局基础图上的多模态、多任务图卷积网络（GCN）来识别文本阅读顺序，并使用后处理聚类和排序算法生成所有文本行的有序序列。英文摘要：Text reading order is a crucial aspect in the output of an OCR engine, with alarge impact on downstream tasks. Its difficulty lies in the large variation ofdomain specific layout structures, and is further exacerbated by real-worldimage degradations such as perspective distortions. We propose a lightweight,scalable and ge
