Meta has launched the Meta Segment Anything Model 2 (SAM 2), an advanced version of its object segmentation technology, which now supports both videos and images.
Released under the Apache 2.0 license, SAM 2 and its dataset, SA-V, are now accessible for public use and innovation.
A web-based demo also showcases the model's capabilities, check it out here!
Here are the following features of SAM 2, that will change how you edit videos or images!
Unified Model for Images and Videos: SAM 2 is the first model to offer real-time, promptable object segmentation for both images and videos. This unification allows seamless application across different visual media.
Enhanced Performance: SAM 2 surpasses previous models in image segmentation accuracy and offers superior video segmentation, requiring significantly less interaction time. It can segment any object in any video or image without custom adaptation, a capability known as zero-shot generalization.
Broad Applications: SAM 2's potential spans various industries, including content creation, science, and medicine. It can enhance video editing, aid in research, and support autonomous vehicle systems by offering faster annotation tools and new interaction methods for live video.
Since its initial release, SAM has revolutionized object segmentation. It has been integrated into Meta's apps like Instagram.
This model is going to save millions of hours in human annotation time and find applications in diverse fields such as marine science, satellite imagery analysis, and medical diagnostics.
Mark Zuckerberg emphasized the transformative potential of open-source AI in enhancing productivity, creativity, and quality of life, aligning with Meta's vision of driving economic growth and scientific advancements.
Memory Mechanism: SAM 2 introduces a memory component that enables accurate segmentation across video frames by recalling previously processed information.
Streaming Architecture: This design allows real-time processing of long videos, making SAM 2 efficient for practical applications like robotics and annotation.
Multiple Mask Predictions: To handle ambiguity, SAM 2 can output multiple valid masks and select the most appropriate one based on user prompts and confidence levels.
The SA-V dataset is a significant leap forward, containing 51,000 videos and over 600,000 masklet annotations.
It offers comprehensive coverage of diverse objects and scenarios from 47 countries, making it the largest video segmentation dataset available.
Developing SAM 2 involved creating a new task, model, and dataset. The model supports promptable visual segmentation, which generalizes the image segmentation task to video.
The architecture allows for iterative refinement and accurate mask predictions across video frames.
The SA-V dataset was built using an interactive model-in-the-loop setup with human annotators, significantly speeding up the annotation process.
SAM 2 is set to unlock new possibilities for AI research and industry applications.
Its fast inference capabilities can inspire innovative uses in real-time video interaction, content creation, and scientific research.
By sharing SAM 2's code, weights, and dataset, Meta aims to foster further advancements in the AI community.
