Text spotting in natural scene images is of great importance for many image understanding tasks. It includes two sub-tasks: text detection and recognition. In this work, we propose a unified network that simultaneously localizes and recognizes text with a single forward pass, avoiding intermediate processes such as image cropping and feature re-calculation, word separation, and character grouping.
In contrast to existing approaches that consider text detection and recognition as two distinct tasks and tackle them one by one, the proposed framework settles these two tasks concurrently. The whole framework can be trained end-to-end and is able to handle text of arbitrary shapes. The convolutional features are calculated only once and shared by both detection and recognition modules. Through multi-task training, the learned features become more discriminate and improve the overall performance. By employing the $2$D attention model in word recognition, the irregularity of text can be robustly addressed. It provides the spatial location for each character, which not only helps local feature extraction in word recognition, but also indicates an orientation angle to refine text localization. Our proposed method has achieved state-of-the-art performance on several standard text spotting benchmarks, including both regular and irregular ones.

野外文本识别包括检测和识别图像中出现的文本(例如,标志牌、交通信号或衣服或物体中的品牌)。这是一个具有挑战性的问题,因为文本出现的上下文的复杂性(不均匀的背景,阴影,遮挡,透视扭曲等)。只有少数方法尝试利用文本与其周围环境之间的关系来更好地识别场景中的文本。在本文中,我们提出了一个用于文本识别的视觉上下文数据集,其中公开可用的数据集COCO-text [Veit et al. 2016]已经扩展了有关场景的信息(例如图像中出现的对象和地点),使研究人员能够在他们的文本识别系统中包含文本和场景之间的语义关系,并为这些方法提供一个通用框架。对于图像中的每个文本,我们提取三种上下文信息:场景中的对象,图像位置标签和文本图像描述(标题)。我们使用最先进的现成可用工具来提取这些额外信息。由于这些信息具有文本形式,因此可以将文本相似性或语义关系方法用于文本识别系统,无论是作为后处理还是端到端的训练策略。我们的数据可在https://git.io/JeZTb上公开获取。

我们介绍了一种算法,字级的文本发现,能够准确可靠地确定文本的单个单词的边界区域“在野外”。我们的系统是由两个卷积神经网络级联而成。第一个网络是完全卷积的,负责检测包含文本的区域。这导致输入图像的非常可靠但可能不准确的分割。第二个网络(受流行的YOLO架构的启发)分析第一阶段产生的每个片段,并预测包含单个单词的定向矩形区域。不需要后处理(例如文本行分组)。在Titan X GPU上处理1000 x 560图像的执行时间为450 ms,我们的系统在ICDAR 2015 Incidental Scene Text数据集基准测试中获得了迄今为止已发布算法中的最高分数。
