Segment Any Anomaly

📢 Latest News
🌟 Our paper has been officially accepted by IEEE Transactions on Cybernetics! Check out the formal publication.

This repository contains the official implementation of Segment Any Anomaly without Training via Hybrid Prompt Regularization, SAA+.

SAA+ aims to segment any anomaly without the need for training. We achieve this by adapting existing foundation models, namely Grounding DINO andSegment Anything, with hybrid prompt regularization.

🔥What's New

• We have added a Huggingface demo. Enjoy it~
• We have updated the colab demo. Enjoy it~
• We have updated this repository for SAA+.
• We have published Segment Any Anomaly without Training via Hybrid Prompt Regularization, SAA+.

💎Framework

We found that a simple assembly of foundation models suffers from severe language ambiguity. Therefore, we introduce hybrid prompts derived from domain expert knowledge and target image context to alleviate the language ambiguity. The framework is illustrated below:

Quick Start

🏦Dataset Preparation

We evaluate SAA+ on four public datasets: MVTec-AD, VisA, KSDD2, and MTD. Additionally, SAA+ was a winning team in the VAND workshop, which offers a specified dataset, VisA-Challenge. To prepare the datasets, please follow the instructions below:

By default, we save the data in the ../datasets directory.

cd $ProjectRoot # e.g., /home/SAA cd .. mkdir datasets cd datasets

Then, follow the corresponding instructions to prepare individual datasets:

• MVTec-AD
• VisA-Public
• VisA-Challenge
• KSDD2
• MTD

🔨Environment Setup

You can use our script for one-click setup of the environment and downloading the checkpoints.

cd $ProjectRoot bash install.sh

📄Repeat the public results

MVTec-AD

VisA-Public

python run_VisA_public.py

VisA-Challenge

python run_VAND_workshop.py

The submission files can be found in ./result_VAND_workshop/visa_challenge-k-0/0shot.

🎯Performance

🔨 Todo List

We have planned the following features to be added in the near future:

• Update repository for SAA+
• Detail the zero-shot anomaly detection framework.
• Evaluate on other image anomaly detection datasets.
• Add UI for easy evaluation.
• Update Colab demo.
• HuggingFace demo.
