Customizing Visual-Language Foundation Models for Multi-modal Anomaly Detection and Reasoning

ArXiv-Paper

Setup environment:

Install packages for your virtual environment:

pip install -r requirements.txt

Set up API keys for openai (Non-Free GPT-4Vision API Usage) and google (for Free Gemini Vision API Usage) on terminal or .bashrc:

export OPENAI_API_KEY=<your key>
export GOOGLE_API_KEY=<your key>

Dataset Preparation:

MVTecAD

• Download link: MVTecAD-Website
• Please put the dataset under the folder datasets/MVTecAD

Evaluation Scripts:

Eval on Gemini

python main_gemini.py --dataset "datasets/MVTecAD/vlm_for_ad_dataset.json" --cache "./output/answer_genmini.json" --output "./output/answer_5.json" --google_api_key 'ADD_YOUR_GOOLE_API_HERE’ --prompt_template “./prompt_template/ad_prompt.txt”

Eval on GPT4-Vision

python main_gpt.py --dataset "datasets/MVTecAD/vlm_for_ad_dataset.json" --cache "./output/answer_gpt4v.json" --output "./output/answer_gpt4v.json" --openai_api_key ‘ADD_YOUR_OPENAI_API_HERE’ --prompt_template “./prompt_template/ad_prompt.txt”

Eval on InternVL2

• Follow the official guidance to set up the environment for InternVL2 and download the checkpoints. (By default, we used InternVL2-8B.)

python main_internvl2.py --model "~/path/to/InternVL2-8B" --dataset "datasets/MVTecAD/vlm_for_ad_dataset.json" --cache "./output/answer_internvl2_8b.json" --output "./output/answer_internvl2_8b.json"

Eval on Qwen2VL

• Follow the official repo to set up the environment for Qwen2VL and download the checkpoints. (By default, we used Qwen2-VL-7B-Instruct.)

python main_qwenvl2.py --model "~/path/to/Qwen2-VL-7B-Instruct" --dataset "datasets/MVTecAD/vlm_for_ad_dataset.json" --cache "./output/answer_qwenvl2_7b.json" --output "./output/answer_qwenvl2_7b.json"
