Say As You Wish: Fine-grained Control of Image Caption Generation with Abstract Scene Graphs

This repository contains PyTorch implementation of our paper Say As You Wish: Fine-grained Control of Image Caption Generation with Abstract Scene Graphs (CVPR 2020).

Prerequisites

Python 3 and PyTorch 1.3.

# clone the repository
git clone https://github.com/cshizhe/asg2cap.git
cd asg2cap
# clone caption evaluation codes
git clone https://github.com/cshizhe/eval_cap.git
export PYTHONPATH=$(pwd):${PYTHONPATH}

Training & Inference

cd controlimcap/driver

# support caption models: [node, node.role, 
# rgcn, rgcn.flow, rgcn.memory, rgcn.flow.memory]
# see our paper for details
mtype=rgcn.flow.memory 

# setup config files
# you should modify data paths in configs/prepare_*_imgsg_config.py
python configs/prepare_coco_imgsg_config.py $mtype
resdir='' # copy the output string of the previous step

# training
python asg2caption.py $resdir/model.json $resdir/path.json $mtype --eval_loss --is_train --num_workers 8

# inference
python asg2caption.py $resdir/model.json $resdir/path.json $mtype --eval_set tst --num_workers 8

Datasets

Annotations

Annotations for MSCOCO and VisualGenome datasets can be download from GoogleDrive.

• (Image, ASG, Caption) annotations: regionfiles/image_id.json

JSON Format:
{
	"region_id": {
		"objects":[
			{
	     		"object_id": int, 
	     		"name": str, 
	     		"attributes": [str],
				"x": int,
				"y": int, 
				"w": int, 
				"h": int
			}],
  	  "relationships": [
			{
				"relationship_id": int,
				"subject_id": int,
				"object_id": int,
				"name": str
			}],
  	  "phrase": str,
  }
}

• vocabularies int2word.npy: [word] word2int.json: {word: int}

• data splits: public_split directory trn_names.npy, val_names.npy, tst_names.npy

Features

Features for MSCOCO and VisualGenome datasets are available at BaiduNetdisk (code: 6q32).

We also provide pretrained models and codes to extract features for new images.

• Global Image Feature: the last mean pooling feature of ResNet101 pretrained on ImageNet

format: npy array, shape=(num_fts, dim_ft) corresponding to the order in data_split names

• Region Image Feature: fc7 layer of Faster-RCNN pretrained on VisualGenome

format: hdf5 files, "image_id".jpg.hdf5

key: 'image_id'.jpg

attrs: {"image_w": int, "image_h": int, "boxes": 4d array (x1, y1, x2, y2)}
