# SAM 2

> Promptable visual segmentation model for images and real-time video tracking.

Meta's Segment Anything Model 2 (SAM 2) is a computer vision foundation model that segments and tracks visual objects across images and video frames. Users can prompt the model with clicks or bounding boxes on a single frame, and it propagates masks throughout the entire video sequence in real time.

## What it is for

- Track and isolate moving objects across video frames without manual rotoscoping
- Generate cutouts and green-screen masks for video editing and compositing
- Blur or pixelate specific sensitive subjects across video footage
- Segment multiple objects simultaneously in computer vision pipelines

## Features

- Zero-shot promptable segmentation via clicks, bounding boxes, or masks
- Streaming memory architecture for real-time video tracking
- Multi-object tracking support with independent per-object inference
- Automatic mask generation across entire images
- Pretrained checkpoints ranging from tiny to large
- Official open-source web demo interface and backend code

## Why it was saved

- [@mardan_king, 19 October 2024](https://www.instagram.com/reel/DBTaN8Zu6rf/): Eliminates tedious manual rotoscoping by allowing users to isolate, blur, pixelate, or remove objects in video clips in seconds.
