Open Source Video Segmentation with SAM2 (Python Code Included)

Full article: How to Use SAM 2 for Video Segmentation (roboflow.com)

Segment Anything Model 2 (SAM 2) is a groundbreaking model that brings unified video and image segmentation under one roof. While the original SAM was a powerful tool for image segmentation, SAM 2 takes it a step further, addressing the unique challenges that video segmentation presents.

The Challenges of Video Segmentation

Video segmentation is significantly more complex than image segmentation due to several factors:

• Object Motion and Deformation: Objects in videos move, change shape, and undergo occlusions, making it difficult to maintain consistent segmentation across frames.
• Lighting and Quality Variations: Lighting changes and the lower quality of video frames due to camera motion, blur, and resolution loss introduce additional segmentation challenges.
• Temporal Consistency: Ensuring that an object is consistently segmented across different frames is a major hurdle.

SAM 2 addresses these challenges by providing improved accuracy with fewer interactions, making it a powerful tool for video segmentation tasks.
