What are the key capabilities of SAM 2?

SAM 2 can segment any object in images and videos, track objects across video frames, handle unfamiliar objects through zero-shot learning, and operate in real-time. It outperforms existing models in both image and video segmentation tasks.

How does SAM 2 differ from the original SAM?

While the original SAM focused mainly on image segmentation, SAM 2 extends capabilities to video. It includes a per-session memory module that allows it to track objects across video frames, even if they temporarily disappear from view.

Is SAM 2 available for public use?

Yes, Meta has released SAM 2 under an Apache 2.0 license. The pretrained model, code, and associated SA-V dataset are publicly available for researchers and developers to use and build upon.

What are some potential applications of SAM 2?

SAM 2 has diverse applications including video editing, autonomous vehicles, robotics, scientific research, augmented reality, and data annotation. Its ability to segment objects in real-time across both images and videos makes it valuable in various industries.

What dataset was used to train SAM 2?

SAM 2 was trained on a large and diverse set of videos and masklets, including the SA-V dataset. This dataset contains over 600,000 masklets collected from about 51,000 videos across 47 countries, providing geographically diverse, real-world scenarios.

How to Use Meta Segment Anything Model 2

Install dependencies: Install PyTorch and other required libraries.

Download the model checkpoint: Download the SAM 2 model checkpoint from the provided GitHub repository.

Import necessary modules: Import torch and the required SAM 2 modules.

Load the SAM 2 model: Use the build_sam2() function to load the SAM 2 model with the downloaded checkpoint.

Prepare your input: Load your image or video that you want to segment.

Create a predictor: For images, create a SAM2ImagePredictor. For videos, use build_sam2_video_predictor().

Set the image/video: Use the predictor's set_image() method for images or init_state() for videos.

Provide prompts: Specify points, boxes, or masks as prompts to indicate the objects you want to segment.

Generate masks: Call the predictor's predict() method for images or add_new_points() and propagate_in_video() for videos to generate segmentation masks.

Process the results: The model will return segmentation masks which you can then use or visualize as needed.
