In this article, we will explore SAM 2, which stands for Segment Anything Model—a sophisticated foundation model designed to enhance prompt visual segmentation capabilities. Developed by Meta, this revolutionary advancement builds upon the previously released SAM, integrating real-time, promptable object segmentation in images and videos. With its ability to operate across previously unseen visual domains, SAM 2 shows great potential in various fields, from video editing to scientific research.
SAM 2 offers several impressive features:
In this guide, we will show you how to run SAM 2 on a GPU machine using RunPod. Here are the essential steps:
Sign up and Deploy GPU on RunPod:
Connect to Jupyter Lab:
Clone the SAM 2 Repository:
git clone https://github.com/facebookresearch/segment-anything.git
cd segment-anything
Install Requirements:
pip install -r requirements.txt
Download Model Checkpoints:
python download_checkpoints.py
Image Processing:
pip install opencv-python-headless
For demonstration, you can use various medical images, such as brain scans or lung nodule images, suitable for segmentation tasks. SAM 2 can precisely identify complex structures, assisting healthcare professionals in making informed decisions.
The GitHub repository also provides sample notebooks covering automatic mask generation and image/video prediction examples. It's advised to explore these notebooks for further understanding.
