SRNet - Editing Text in the Wild

 

Introduction

This is a reproducing of paper Editing Text in the wild by tensorflow, which aims to replace or modify a word in the source image with another one while maintaining its realistic look.

Original paper: Editing Text in the wild by Liang Wu, Chengquan Zhang, Jiaming Liu, Junyu Han, Jingtuo Liu, Errui Ding and Xiang Bai.

The model in this project is a result of my experiment and debugging of the details described in the paper.

A pre-trained vgg19 model is used in this SRNet, which is downloaded from https://github.com/fchollet/deep-learning-models/releases/tag/v0.1 and converted to pb format

Prepare data

Data is completely prepared as described in the paper.

You can refer to and improve Synthtext project to render styled texts on background images. Also need to save some intermediate results as labels while rendering.

According to this paper, you need to prepare 2 input images(i_s, i_t) and 4 label images(t_sk, t_t, t_b, t_f)

In my experiment, I found it easier to train with one more label data(mask_t).

From left to right, from top to bottom are examples of i_s, i_t, t_sk, t_t, t_b, t_f, mask_t

This is our code to generate SRNet data: SRNet-Datagen

 

Train your own dataset

First clone this project

$ git clone https://github.com/youdao-ai/SRNet.git

Once the data is ready, put the images in different directories with the same name.

You can modify the data directories and training parameters in cfg.py as you want.

Then run python3 train.py to start training.

 

Predict

This is our pretrained weight: https://pan.baidu.com/s/1TaliSQ96RtlJLSgpOzkRSA, Extraction code: x3qv

You can predict your own data with

$ python3 predict.py --i_s xxx --i_t xxx --save_dir xxx --checkpoint xxx

If you want to predict a directory of data, just make sure your data i_s and i_t have the same prefix and splited by '_', for example, image1_i_s.png and image1_i_t.png, put them into one directory and

$ python3 predict.py --input_dir xxx --save_dir xxx --checkpoint xxx

Or you can set these path information in cfg.py and just python3 predict.py
