自然图像中文本定位的合成数据

Synthetic Data for Text Localisation in Natural Images

University of Oxford(牛津大学)

Ankush Gupta, Andrea Vedaldi, Andrew Zisserman

摘要:

在本文中,我们介绍了一种新的方法,在自然图像中的文本检测。该方法包括两个贡献:第一,一个快速和可扩展的引擎,以生成杂波中的文本合成图像。该引擎以自然的方式将合成文本覆盖到现有的背景图像上,考虑到本地3D场景几何形状。其次,我们使用合成图像来训练全卷积回归网络(FCRN),该网络在图像中的所有位置和多个尺度上有效地执行文本检测和边界框回归。我们讨论了FCRN与最近推出的YOLO检测器以及其他基于深度学习的端到端目标检测系统的关系。由此产生的检测网络在自然图像中的文本检测方面明显优于当前的方法,在标准ICDAR 2013基准上实现了84.2%的F测量。此外,它可以在GPU上每秒处理15张图像。

英文摘要:

In this paper we introduce a new method for text detection in natural images. The method comprises two contributions: First, a fast and scalable engine to generate synthetic images of text in clutter. This engine overlays synthetic text to existing background images in a natural way, accounting for the local 3D scene geometry. Second, we use the synthetic images to train a Fully-Convolutional Regression Network (FCRN) which efficiently performs text detection and bounding-box regression at all locations and multiple scales in an image. We discuss the relation of FCRN to the recently-introduced YOLO detector, as well as other end-to-end object detection systems based on deep learning. The resulting detection network significantly out performs current methods for text detection in natural images, achieving an F-measure of 84.2% on the standard ICDAR 2013 benchmark. Furthermore, it can process 15 images per second on a GPU.
