🏃 Fast Segment Anything 🤗"
description = """This is a demo on Github project 🏃 [Fast Segment Anything Model](https://github.com/CASIA-IVA-Lab/FastSAM).
🎯 Upload an Image, segment it with Fast Segment Anything (Everything mode). The other modes will come soon.
⌛️ It takes about 4~ seconds to generate segment results. The concurrency_count of queue is 1, please wait for a moment when it is crowded.
🚀 To get faster results, you can use a smaller input size and leave high_visual_quality unchecked.
📣 You can also obtain the segmentation results of any Image through this Colab: [![Open in Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1oX14f6IneGGw612WgVlAiy91UHwFAvr9?usp=sharing)
😚 A huge thanks goes out to the @HuggingFace Team for supporting us with GPU grant.
🏠 Check out our [Model Card 🏃](https://huggingface.co/An-619/FastSAM)
