+# Faster Segment Anything(MobileSAM)
+
+Official PyTorch Implementation of the <a href="https://github.com/ChaoningZhang/MobileSAM">.
+
+
+**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.
