+## **SegGPT Usage**
+- We release the [SegGPT model](https://huggingface.co/BAAI/SegGPT/blob/main/seggpt_vit_large.pth) and inference code for segmentation everything, as well as some example images and videos.
+### Installation
+```
+git clone https://github.com/baaivision/Painter
+cd Painter/SegGPT/SegGPT_inference && wget https://huggingface.co/BAAI/SegGPT/resolve/main/seggpt_vit_large.pth
+pip install -r requirements.txt
+```
+### Usage
+Everything in an image with a prompt.
+```
+python seggpt_inference.py \
+--input_image examples/hmbb_2.jpg \
+--prompt_image examples/hmbb_1.jpg \
+--prompt_target examples/hmbb_1_target.png \
+--output_dir ./
+```
+
+Everything in an image with multiple prompts.
+```
+python seggpt_inference.py \
+--input_image examples/hmbb_3.jpg \
+--prompt_image examples/hmbb_1.jpg examples/hmbb_2.jpg \
+--prompt_target examples/hmbb_1_target.png examples/hmbb_2_target.png \
+--output_dir ./
+```
+
+Everything in a video using a prompt image.
+```
+python seggpt_inference.py \
+--input_video examples/video_1.mp4 \
+--prompt_image examples/video_1.jpg \
+--prompt_target examples/video_1_target.png \
+--output_dir ./
+```
+
+Everything in a video using the first frame as the prompt.
+```
+python seggpt_inference.py \
+--input_video examples/video_1.mp4 \
+--prompt_target examples/video_1_target.png \
+--output_dir ./
+```
+
+Processing a long video with prompts from both a target image and the predictions of the previous NUM_FRAMES frames.
+```
+NUM_FRAMES=4
+python seggpt_inference.py \
+--input_video examples/video_3.mp4 \
+--prompt_target examples/video_3_target.png \
+--num_frames $NUM_FRAMES \
