SAM3-UNet

SAM3 segments brilliantly, but adapting it to medical or remote sensing tasks with full fine-tuning is costly. SAM3-UNet is a simplified variant that adapts Segment Anything Model 3 at low cost with the SAM3 image encoder, a light adapter and a U-Net-style decoder.

Training a few parameters transfers it to downstream segmentation with low memory use.

Features

Low cost:Parameter-efficient.

U-Net decoder:Lightweight.

Downstream:Medical, remote sensing and more.
