Exploring the Capacity of an Orderless Box Discretization Network for Multi-orientation Scene Text Detection [article]

Yuliang Liu, Tong He, Hao Chen, Xinyu Wang, Canjie Luo, Shuaitao Zhang, Chunhua Shen, Lianwen Jin
2021 arXiv   pre-print
Multi-orientation scene text detection has recently gained significant research attention. Previous methods directly predict words or text lines, typically by using quadrilateral shapes.  ...  Here we solve this problem by proposing a new method, Orderless Box Discretization (OBD), which first discretizes the quadrilateral box into several key edges containing all potential horizontal and vertical  ...  Multi-orientation scene text detection is one of the most important representations for the task of scene text detection because straight text occupies the majority of the scene text.  ...

What If We Only Use Real Datasets for Scene Text Recognition? Toward Scene Text Recognition With Fewer Labels [article]

Jeonghun Baek, Yusuke Matsui, Kiyoharu Aizawa
2021 arXiv   pre-print
Scene text recognition (STR) task has a common practice: All state-of-the-art STR models are trained on large synthetic data.  ...  In contrast to this practice, training STR models only on fewer real labels (STR with fewer labels) is important when we have to train STR models without synthetic data: for handwritten or artistic texts  ...  Omnidirectional scene text detec- tion with sequential-free box discretization.
