Copy-Pasting GAN

A TensorFlow implementation of paper Object Discovery with a Copy-Pasting GAN.

Requirements

• Python 3.7
• TensorFlow 1.13.1

Run

1. Prepare dataset

   1. Prepare foreground and background images(jpg format only);
   2. Put foreground images into data/plane_sky/plane;
   3. Put background images into data/plane_sky/sky;
   4. Resize foreground and background images to $240\times240$;(You can use img_utils.py in utils folder);
   • You can change image format in train.py and utils/img_utils.py;
   • You can change image folder in cfgs.py;

2. Train with python main.py.

3. You can find checkpoints and saved images in logs. :)

Results

Foreground	Background	Random selected foreground
Random generated Mask	Grounded Fake (with random mask)	Predicted mask from D (for Grounded Fake)
Predicted mask from G (for Foreground)	Anti-shortcut (foreground+random foreground)	Predicted mask from D (for Anti-shortcut)
Predicted mask from D (for Foreground)	Composited image (foreground+background)	Predicted mask from D (for Composited image)
