Text Image Augmentation

Build Status

A general geometric augmentation tool for text images in the CVPR 2020 paper "Learn to Augment: Joint Data Augmentation and Network Optimization for Text Recognition". We provide the tool to avoid overfitting and gain robustness of text recognizers.

Note that this is a general toolkit. Please customize for your specific task. If the repo benefits your work, please cite the papers.

Requirements

Demo

  • Distortion

  • Stretch

  • Perspective

Speed

To transform an image with size (H:64, W:200), it takes less than 14ms using a 2.5GHz CPU. It is possible to accelerate the process by calling multi-process batch samplers in an on-the-fly manner, such as setting "num_workers" in PyTorch.

Attention

Modify from https://github.com/Canjie-Luo/Text-Image-Augmentation.git.

关于注释

您好!
请问您代码中的注释哪些模块是必需的呀?我看 demo 还有导入 augment 中被注释掉的模块.
您会更新一份精简版的代码吗?
多谢了!

弯曲的文字超出图片区域

你好，我想通过该代码生成一些弯曲的文字，但是生成之后有部分弯曲的文字超出了图片的边界。请问可以将生成图片size变大，文字大小不变，保证文字在图片里面吗？感谢
