TODO: Release the PerSAM-assisted Dreambooth for better fine-tuning Stable Diffusion 📌.
We release the code of PerSAM and PerSAM-F 🔥. Check our video here!
We release a new dataset for personalized segmentation, PerSeg 🔥.

Introduction

How to customize SAM to automatically segment your pet dog in a photo album?

In this project, we propose a training-free Personalization approach for Segment Anything Model (SAM), termed as PerSAM. Given only a single image with a reference mask, PerSAM can segment specific visual concepts, e.g., your pet dog, within other images or videos without any training. For better performance, we further present an efficient one-shot fine-tuning variant, PerSAM-F. We freeze the entire SAM and introduce two learnable mask weights, which only trains 2 parameters within 10 seconds.

Besides, our approach can be utilized to assist DreamBooth in fine-tuning better Stable Diffusion for personalized image synthesis. We adopt PerSAM to segment the target object in the user-provided few-shot images, which eliminates the background disturbance and benefits the target representation learning.

Requirements

Installation

Clone the repo and create a conda environment:

git clone https://github.com/ZrrSkywalker/Personalize-SAM.git
cd Personalize-SAM

conda create -n persam python=3.8
conda activate persam

pip install -r requirements.txt

Similar to Segment Anything, our code requires pytorch>=1.7 and torchvision>=0.8. Please follow the instructions here to install both PyTorch and TorchVision dependencies.

Preparation

Please download our constructed dataset PerSeg for personalized segmentation from Google Drive or Baidu Yun (code 222k), and the pre-trained weights of SAM from here. Then, unzip the dataset file and organize them as

Getting Started

Personalized Segmentation

For the training-free 🧊 PerSAM, just run:

python persam.py --outdir <output filename>

For 10-second fine-tuning of 🚀 PerSAM-F, just run:

python persam_f.py --outdir <output filename>

After running, the output masks and visualzations will be stored at outputs/<output filename>.

Then, for mIoU evaluation, please run:

python eval_miou.py --pred_path <output filename>

Personalized Stable Diffusion

Our approach can enhance DreamBooth to better personalize Stable Diffusion for text-to-image generation.

Comming soon.
