# Segment Anything Model from Facebook

This is an implementation of the Segment Anything model from Facebook using PyTorch. The model can be used for image segmentation tasks to separate foreground objects from the background.

## How to Use the Model

We have implemented an API using FastAPI and Uvicorn to provide an easy-to-use interface for the Segment Anything model. The API allows users to send image files to the model and receive the segmented images in response.

To use the model, follow these steps:

1. Clone this repository to your local machine.
2. Install the required packages by running `pip install -r requirements.txt`.
3. Start the API server by running `python server.py`.
4. Send a POST request to `http://localhost:8000/PATH_USED_IN_CODE` with the image file attached as form data.

The response from the API will be a JSON object containing the segmented image as a base64-encoded string.

## How the Model Works

The Segment Anything model uses a fully convolutional neural network to perform image segmentation. The model takes an image as input and outputs a segmentation map, where each pixel in the map is assigned a label indicating whether it belongs to the foreground or background.

The model is trained on a large dataset of annotated images using a binary cross-entropy loss function. During training, the weights of the network are adjusted to minimize the difference between the predicted segmentation map and the ground truth segmentation map.
