Segment Anything Model (SAM) variants including:
- CoralSCOP
- RepViT-SAM
- EdgeSAM
- MobileSAM
- SAM (original)
combined in the same API (to make life easier).
For more information on different SAM variants, please see the following:
The code requires python>=3.8
, 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.
Install xSAM:
pip install x-segment-anything
The SAM models can be loaded in the following ways:
from x_segment_anything import sam_model_registry, SamPredictor
model_type = "vit_b_coralscop"
model_type = "repvit"
model_type = "edge_sam"
model_type = "vit_t"
model_type = "vit_b"
model_type = "vit_l"
model_type = "vit_h"
sam_checkpoint = "path_to_checkpoints/model_x_weights.pt"
device = "cuda" if torch.cuda.is_available() else "cpu"
x_sam = sam_model_registry[model_type](checkpoint=sam_checkpoint)
x_sam.to(device=device)
x_sam.eval()
predictor = SamPredictor(x_sam)
predictor.set_image(<your_image>)
masks, _, _ = predictor.predict(<input_prompts>)
or generate masks for an entire image:
from x_segment_anything import SamAutomaticMaskGenerator
mask_generator = SamAutomaticMaskGenerator(x_sam)
masks = mask_generator.generate(<your_image>)
For convenience, The following model checkpoints are available in the sam_model_urls
dictionary and can be downloaded
in python:
import requests
from x_segment_anything.build_sam import sam_model_urls
def download_asset(asset_url, asset_path):
response = requests.get(asset_url)
with open(asset_path, 'wb') as f:
f.write(response.content)
model_path = "vit_b_coral_scop.pt"
model_path = "repvit.pt"
model_path = "edge_sam.pt"
model_path = "edge_sam_3x.pt"
model_path = "vit_t.pt"
model_path = "vit_b.pt"
model_path = "vit_l.pt"
model_path = "vit_h.pt"
model = model_path.split(".")[0]
model_url = sam_model_urls[model]
download_asset(model_url, model_path)
