MTRNet: A Generic Scene Text Eraser
Text removal algorithms have been proposed for uni-lingual scripts with
regular shapes and layouts. However, to the best of our knowledge, a generic
text removal method which is able to remove all or user-specified text regions
regardless of font, script, language or shape is not available. Developing such
a generic text eraser for real scenes is a challenging task, since it inherits
all the challenges of multi-lingual and curved text detection and inpainting.
To fill this gap, we propose a mask-based text removal network (MTRNet). MTRNet
is a conditional adversarial generative network (cGAN) with an auxiliary mask.
The introduced auxiliary mask not only makes the cGAN a generic text eraser,
but also enables stable training and early convergence on a challenging
large-scale synthetic dataset, initially proposed for text detection in real
scenes. What's more, MTRNet achieves state-of-the-art results on several
real-world datasets including ICDAR 2013, ICDAR 2017 MLT, and CTW1500, without
being explicitly trained on this data, outperforming previous state-of-the-art
methods trained directly on these datasets.Comment: Presented at ICDAR2019 Conferenc
