Semantic Image Synthesis via Adversarial Learning

This is a PyTorch implementation of the paper Semantic Image Synthesis via Adversarial Learning.

Requirements

• PyTorch 0.2
• Torchvision
• Pillow
• fastText.py (Note: if you have a problem when loading a pretrained model, try my fixed code)
• NLTK

Pretrained word vectors for fastText

Download a pretrained English word vectors. You can see the list of pretrained vectors on this page.

Datasets

• Oxford-102 flowers: images and captions
• Caltech-200 birds: images and captions

The caption data is from this repository. After downloading, modify CONFIG file so that all paths of the datasets point to the data you downloaded.

Run

• scripts/train_text_embedding_[birds/flowers].sh
  Train a visual-semantic embedding model using the method of Kiros et al..
• scripts/train_[birds/flowers].sh
  Train a GAN using a pretrained text embedding model.
• scripts/test_[birds/flowers].sh
  Generate some examples using original images and semantically relevant texts.
