SegGPT is a vision generalist on image segmentation, quite like GPT for computer vision ✨ 
It comes with the last release of 🤗 Transformers.  
🎁 Technical details, demo and how-to's under this!

SegGPT is an extension of the Painter, where you speak to images with images: the model takes in an image prompt, transformed version of the image prompt, the actual image you want to see the same transform, and expected to output the transformed image.

SegGPT consists of a vanilla ViT with a decoder on top (linear, conv, linear). The model is trained on diverse segmentation examples, where they provide example image-mask pairs, the actual input to be segmented, and the decoder head learns to reconstruct the mask output. 👇🏻

This generalizes pretty well! The authors do not claim state-of-the-art results as the model is mainly used zero-shot and few-shot inference. They also do prompt tuning, where they freeze the parameters of the model and only optimize the image tensor (the input context).

Thanks to 🤗 Transformers you can use this model easily! See [here](https://t.co/U5pVpBhkfK).

I have built an app for you to try it out. I combined SegGPT with Depth Anything Model, so you don't have to upload image mask prompts in your prompt pair 🤗
