Kolors-IP-Adapter-Plus weights and inference code

     

📖 Introduction

We provide IP-Adapter-Plus weights and inference code based on Kolors-Basemodel. Examples of Kolors-IP-Adapter-Plus results are as follows:

Our improvements

• A stronger image feature extractor. We employ the Openai-CLIP-336 model as the image encoder, which allows us to preserve more details in the reference images
• More diverse and high-quality training data: We construct a large-scale and high-quality training dataset inspired by the data strategies of other works. We believe that paired training data can effectively improve performance.

📊 Evaluation

For evaluation, we create a test set consisting of over 200 reference images and text prompts. We invite several image experts to provide fair ratings for the generated results of different models. The experts rate the generated images based on four criteria: visual appeal, text faithfulness, image faithfulness, and overall satisfaction. Image faithfulness measures the semantic preservation ability of IP-Adapter on reference images, while the other criteria follow the evaluation standards of BaseModel. The specific results are summarized in the table below, where Kolors-IP-Adapter-Plus achieves the highest overall satisfaction score.

Model	Average Overall Satisfaction	Average Image Faithfulness	Average Visual Appeal	Average Text Faithfulness
SDXL-IP-Adapter-Plus	2.29	2.64	3.22	4.02
Midjourney-v6-CW	2.79	3.0	3.92	4.35
Kolors-IP-Adapter-Plus	3.04	3.25	4.45	4.30

The ip_scale parameter is set to 0.3 in SDXL-IP-Adapter-Plus, while Midjourney-v6-CW utilizes the default cw scale.

Kolors-IP-Adapter-Plus employs chinese prompts, while other methods use english prompts.

git clone https://github.com/Kwai-Kolors/Kolors
cd Kolors
conda create --name kolors python=3.8
conda activate kolors
pip install -r requirements.txt
python3 setup.py install

2. Weights download link：

huggingface-cli download --resume-download Kwai-Kolors/Kolors-IP-Adapter-Plus --local-dir weights/Kolors-IP-Adapter-Plus

or

git lfs clone https://huggingface.co/Kwai-Kolors/Kolors-IP-Adapter-Plus weights/Kolors-IP-Adapter-Plus

3. Inference：

python ipadapter/sample_ipadapter_plus.py ./ipadapter/https://raw.githubusercontent.com/junqiangwu/Kolors/master/ipadapter/asset/test_ip.jpg "穿着黑色T恤衫，上面中文绿色大字写着“可图”"

python ipadapter/sample_ipadapter_plus.py ./ipadapter/https://raw.githubusercontent.com/junqiangwu/Kolors/master/ipadapter/asset/test_ip2.png "一只可爱的小狗在奔跑"

# The image will be saved to "scripts/outputs/"

Note

The IP-Adapter-FaceID model based on Kolors will also be released soon!
