ManiGAN

Pytorch implementation for ManiGAN: Text-Guided Image Manipulation. The goal is to semantically edit parts of an image according to the given text while preserving text-irrelevant contents.

Data

  1. Download the preprocessed metadata for bird and coco, and save both into data/
  2. Download bird dataset and extract the images to data/birds/
  3. Download coco dataset and extract the images to data/coco/

Training

All code was developed and tested on CentOS 7 with Python 3.7 (Anaconda) and PyTorch 1.1.

DAMSM model includes text encoder and image encoder

  • Pre-train DAMSM model for bird dataset:
python pretrain_DAMSM.py --cfg cfg/DAMSM/bird.yml --gpu 0
  • Pre-train DAMSM model for coco dataset:
python pretrain_DAMSM.py --cfg cfg/DAMSM/coco.yml --gpu 1

ManiGAN, main module

  • Train main module for bird dataset:
python main.py --cfg cfg/train_bird.yml --gpu 2
  • Train main module for coco dataset:
python main.py --cfg cfg/train_coco.yml --gpu 3

*.yml files include configuration for training and testing.

ManiGAN, detail correction module (DCM)

Save trained main module to models/

  • Train DCM for bird dataset:
python DCM.py --cfg cfg/train_bird.yml --gpu 2
  • Train DCM for coco dataset:
python DCM.py --cfg cfg/train_coco.yml --gpu 3

Pretrained DAMSM Model

Pretrained ManiGAN Model

Testing

  • Test ManiGAN model for bird dataset:
python main.py --cfg cfg/eval_bird.yml --gpu 4
  • Test ManiGAN model for coco dataset:
python main.py --cfg cfg/eval_coco.yml --gpu 5

Evaluation

Code Structure

  • code/main.py: the entry point for training the main module and testing ManiGAN.
  • code/DCM.py: the entry point for training the DCM.
  • code/trainer.py: creates the main module networks, harnesses and reports the progress of training.
  • code/trainerDCM.py: creates the DCM networks, harnesses and reports the progress of training.
  • code/model.py: defines the architecture of ManiGAN.
  • code/attention.py: defines the spatial and channel-wise attentions.
  • code/VGGFeatureLoss.py: defines the architecture of the VGG-16.
  • code/datasets.py: defines the class for loading images and captions.
  • code/pretrain_DAMSM.py: trains the text and image encoders, harnesses and reports the progress of training.
  • code/miscc/losses.py: defines and computes the losses for the main module.
  • code/miscc/lossesDCM.py: defines and computes the losses for DCM.
  • code/miscc/config.py: creates the option list.
  • code/miscc/utils.py: additional functions.
