Segment Anything Model 2
Overview :
Segment Anything Model 2 (SAM 2) is a visual segmentation model launched by Meta's AI research division, FAIR. It achieves real-time video processing through a simple transformer architecture and streaming memory design. The model builds a loop data engine through user interaction, gathering the largest video segmentation dataset to date, SA-V. SAM 2 is trained on this dataset, delivering outstanding performance across a wide range of tasks and visual domains.
Target Users :
SAM 2 is designed for researchers and developers who require visual segmentation in images and videos, particularly those needing real-time video processing. Its powerful performance and ease of use make it a top choice in its field.
