# SAM
|
|
|
|
## Overview
|
|
|
|
SAM (Segment Anything Model) was proposed in [Segment Anything](https://arxiv.org/pdf/2304.02643v1.pdf) by Alexander Kirillov, Eric Mintun, Nikhila Ravi, Hanzi Mao, Chloe Rolland, Laura Gustafson, Tete Xiao, Spencer Whitehead, Alex Berg, Wan-Yen Lo, Piotr Dollar, Ross Girshick.
|
|
|
|
The model can be used to predict segmentation masks of any object of interest given an input image.
|
|
|
|
|
|
|
|
The abstract from the paper is the following:
|
|
|
|
*We introduce the Segment Anything (SA) project: a new task, model, and dataset for image segmentation. Using our efficient model in a data collection loop, we built the largest segmentation dataset to date (by far), with over 1 billion masks on 11M licensed and privacy respecting images. The model is designed and trained to be promptable, so it can transfer zero-shot to new image distributions and tasks. We evaluate its capabilities on numerous tasks and find that its zero-shot performance is impressive -- often competitive with or even superior to prior fully supervised results. We are releasing the Segment Anything Model (SAM) and corresponding dataset (SA-1B) of 1B masks and 11M images at \href{https://segment-anything.com}{https://segment-anything.com} to foster research into foundation models for computer vision.*

|
|
Tips:
|
|
|
|
- The model predicts binary masks that states the presence or not of the object of interest given an image.
|
|
- The model predicts much better results if input 2D points and/or input bounding boxes are provided
|
|
- You can prompt multiple points for the same image, and predict a single mask.
|
|
- Fine-tuning the model is not supported yet
|
|
- According to the paper, textual input should be also supported. However, at this time of writing this seems to be not supported according to [the official repository](https://github.com/facebookresearch/segment-anything/issues/4#issuecomment-1497626844).

Below is an example on how to run mask generation given an image and a 2D point:
|
|
|
|
```python
|
|
from PIL import Image
|
|
import requests
|
|
from transformers import SamModelForMaskedGeneration, SamProcessor
|
|
|
|
model = SamModelForMaskedGeneration.from_pretrained("facebook/sam-vit-huge")
|
|
processsor = SamProcessor.from_pretrained("facebook/sam-vit-huge")
|
|
|
|
img_url = "https://huggingface.co/ybelkada/segment-anything/resolve/main/assets/car.png"
|
|
raw_image = Image.open(requests.get(img_url, stream=True).raw).convert("RGB")
|
|
input_points = [[[450, 600]]] # 2D location of a window in the image
|
|
|
|
inputs = processor(raw_image, input_points=input_points, return_tensors="pt").to(device)
|
|
outputs = model(**inputs)
|
|
|
|
masks = processor.image_processor.post_process_masks(
|
|
outputs.pred_masks.cpu(), inputs["original_sizes"].cpu(), inputs["reshaped_input_sizes"].cpu()
|
|
)
|
|
scores = outputs.iou_scores
|
|
```
