ImagenHub: Standardizing the evaluation of conditional image generation models <br> ICLR 2024

ImagenHub is a one-stop library to standardize the inference and evaluation of all the conditional image generation models.

• We define 7 prominent tasks and curate 7 high-quality evaluation datasets for each task.
• We built a unified inference pipeline to ensure fair comparison. We currently support around 30 models.
• We designed two human evaluation scores, i.e. Semantic Consistency and Perceptual Quality, along with comprehensive guidelines to evaluate generated images.
• We provide code for visualization, autometrics and Amazon mechanical turk templates.

🛠️ Installation 🔝

Install from PyPI:

pip install imagen-hub

Or build from source:

git clone https://github.com/TIGER-AI-Lab/ImagenHub.git
cd ImagenHub
conda env create -f env_cfg/imagen_environment.yml
conda activate imagen
pip install -e .

For models like Dall-E, DreamEdit, and BLIPDiffusion, please see Extra Setup

For some models (Stable Diffusion, SDXL, CosXL, etc.), you need to login through huggingface-cli.

Benchmarking

To reproduce our experiment reported in the paper:

Example for text-guided image generation:

python3 benchmarking.py -cfg benchmark_cfg/ih_t2i.yml

Note that the expected output structure would be:

result_root_folder
└── experiment_basename_folder
    ├── input (If applicable)
    │   └── image_1.jpg ...
    ├── model1
    │   └── image_1.jpg ...
    ├── model2
    │   └── image_1.jpg ...
    ├── ...

Then after running the experiment, you can run

python3 visualize.py --cfg benchmark_cfg/ih_t2i.yml

to produce a index.html file for visualization.

The file would look like something like this. We hosted our experiment results on Imagen Museum. <img src="https://i.imgur.com/0uOMhtT.png" width="512" />

Infering one model

import imagen_hub

model = imagen_hub.load("SDXL")
image = model.infer_one_image(prompt="people reading pictures in a museum, watercolor", seed=1)
image

Running Metrics

from imagen_hub.metrics import MetricLPIPS
from imagen_hub.utils import load_image, save_pil_image, get_concat_pil_images

def evaluate_one(model, real_image, generated_image):
  score = model.evaluate(real_image, generated_image)
  print("====> Score : ", score)

image_I = load_image("https://chromaica.github.io/Museum/ImagenHub_Text-Guided_IE/input/sample_102724_1.jpg")
image_O = load_image("https://chromaica.github.io/Museum/ImagenHub_Text-Guided_IE/DiffEdit/sample_102724_1.jpg")
show_image = get_concat_pil_images([image_I, image_O], 'h')

model = MetricLPIPS()
evaluate_one(model, image_I, image_O) # ====> Score :  0.11225218325853348
