Faster Segement Anything (MobileSAM)

<!-- Provide a quick summary of what the model is/does. -->

• Repository: Github - MobileSAM
• Paper: Faster Segment Anything: Towards Lightweight SAM for Mobile Applications
• Demo: HuggingFace Demo

MobileSAM performs on par with the original SAM (at least visually) and keeps exactly the same pipeline as the original SAM except for a change on the image encoder. Specifically, we replace the original heavyweight ViT-H encoder (632M) with a much smaller Tiny-ViT (5M). On a single GPU, MobileSAM runs around 12ms per image: 8ms on the image encoder and 4ms on the mask decoder.

The comparison of ViT-based image encoder is summarzed as follows:

Original SAM and MobileSAM have exactly the same prompt-guided mask decoder:

The comparison of the whole pipeline is summarzed as follows:
