ScrabbleGAN (TensorFlow 2/ Python3)

Implementation of ScrabbleGAN for adversarial generation of handwritten text images in TensorFlow 2.1.

Try it out!

Example on how to train ScrabbleGAN + how to generate images. More details can be found here.

Setup (only tested on MacOS)

1. Download and extract IAM-Handwriting DB and random word list as described in src/dinterface/dinterface.py

   wget --user <user-id> --password <pw> http://www.fki.inf.unibe.ch/DBs/iamDB/data/words/words.tgz 
   wget --user <user-id> --password <pw> http://www.fki.inf.unibe.ch/DBs/iamDB/data/ascii/words.txt
   wget -O random_words.txt https://www.dropbox.com/s/o60ubzh3m163j0x/random_words.txt?dl=0
   tar zxvf words.tgz
   rm -rf words.tgz       
   

2. Move folders into correct position (see File Structure); update file paths in scrabble_gan.gin + main.py

3. Install dependencies (e.g. AWS P3)

Usage

Train model

python3 main.py
