View MoreHow 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.
