GitHub - CASIA-IVA-Lab/FastSAM: Fast Segment Anything

[📕Paper] [🤗HuggingFace Demo] [Colab demo] [Replicate demo & API] [ OpenXLab Demo] [Model Zoo] [BibTeX] [Video Demo]

The Fast Segment Anything Model(FastSAM) is a CNN Segment Anything Model trained using only 2% of the SA-1B dataset published by SAM authors. FastSAM achieves comparable performance with the SAM method at 50× higher run-time speed.

🍇 Updates

2024/6/25 The edge jaggies issue has been slightly improved #231, and the strategy has also been synchronized to the ultralytics project#13939,#13912. The huggingface demo is updated.
2023/11/28 Recommendation: Semantic FastSAM, which add the semantic class labels to FastSAM. Thanks to KBH00 for this valuable contribution.
2023/09/11 Release Training and Validation Code.
2023/08/17 Release OpenXLab Demo. Thanks to OpenXLab Team for help.
2023/07/06 Added to Ultralytics (YOLOv8) Model Hub. Thanks to Ultralytics for help 🌹.
2023/06/29 Support text mode in HuggingFace Space. Thanks a lot to gaoxinge for help 🌹.
2023/06/29 Release FastSAM_Awesome_TensorRT. Thanks a lot to ChuRuaNh0 for providing the TensorRT model of FastSAM 🌹.

2023/06/24 Thanks a lot to Grounding-SAM for Combining Grounding-DINO with FastSAM in Grounded-FastSAM 🌹.

Clone the repository locally:

git clone https://github.com/CASIA-IVA-Lab/FastSAM.git

Create the conda env. The code requires python>=3.7, as well as pytorch>=1.7 and torchvision>=0.8. Please follow the instructions here to install both PyTorch and TorchVision dependencies. Installing both PyTorch and TorchVision with CUDA support is strongly recommended.

conda create -n FastSAM python=3.9
conda activate FastSAM

Install the packages:

cd FastSAM
pip install -r requirements.txt

Install CLIP(Required if the text prompt is being tested.):

pip install git+https://github.com/openai/CLIP.git

First download a model checkpoint.

Then, you can run the scripts to try the everything mode and three prompt modes.

# Everything mode
python Inference.py --model_path ./weights/FastSAM.pt --img_path ./images/dogs.jpg

# Text prompt
python Inference.py --model_path ./weights/FastSAM.pt --img_path ./images/dogs.jpg  --text_prompt "the yellow dog"

# Box prompt (xywh)
python Inference.py --model_path ./weights/FastSAM.pt --img_path ./images/dogs.jpg --box_prompt "[[570,200,230,400]]"

# Points prompt
python Inference.py --model_path ./weights/FastSAM.pt --img_path ./images/dogs.jpg  --point_prompt "[[520,360],[620,300]]" --point_label "[1,0]"

You can use the following code to generate all masks and visualize the results.

from fastsam import FastSAM, FastSAMPrompt

model = FastSAM('./weights/FastSAM.pt')
IMAGE_PATH = './images/dogs.jpg'
DEVICE = 'cpu'
everything_results = model(IMAGE_PATH, device=DEVICE, retina_masks=True, imgsz=1024, conf=0.4, iou=0.9,)
prompt_process = FastSAMPrompt(IMAGE_PATH, everything_results, device=DEVICE)

# everything prompt
ann = prompt_process.everything_prompt()

prompt_process.plot(annotations=ann,output_path='./output/dog.jpg',)

For point/box/text mode prompts, use:

# bbox default shape [0,0,0,0] -> [x1,y1,x2,y2]
ann = prompt_process.box_prompt(bboxes=[[200, 200, 300, 300]])

# text prompt
ann = prompt_process.text_prompt(text='a photo of a dog')

# point prompt
# points default [[0,0]] [[x1,y1],[x2,y2]]
# point_label default [0] [1,0] 0:background, 1:foreground
ann = prompt_process.point_prompt(points=[[620, 360]], pointlabel=[1])

prompt_process.plot(annotations=ann,output_path='./output/dog.jpg',)

You are also welcomed to try our Colab demo: FastSAM_example.ipynb.

Different Inference Options

We provide various options for different purposes, details are in MORE_USAGES.md.

Training from scratch or validation: Training and Validation Code.

We also provide a UI for testing our method that is built with gradio. You can upload a custom image, select the mode and set the parameters, click the segment button, and get a satisfactory segmentation result. Currently, the UI supports interaction with the 'Everything mode' and 'points mode'. We plan to add support for additional modes in the future. Running the following command in a terminal will launch the demo:

# Download the pre-trained model in "./weights/FastSAM.pt"
python app_gradio.py

This demo is also hosted on HuggingFace Space.

Replicate demo has supported all modes, you can experience points/box/text mode.

Two model versions of the model are available with different sizes. Click the links below to download the checkpoint for the corresponding model type.

All result were tested on a single NVIDIA GeForce RTX 3090.
