# YOLOS Object Detection with Gradio
|
2 |
-
|
3 |
-
This Gradio demo uses the pretrained YOLOS transformer (`hustvl/yolos-base`) from Hugging Face Transformers to detect objects in uploaded images.
|
4 |
-
|
5 |
-
## Features
|
6 |
-
- Upload any image
|
7 |
-
- Detect objects with YOLOS
|
8 |
-
- See bounding boxes and object labels
|
9 |
-
- Adjustable confidence threshold
|
10 |
-
|
11 |
-
## Run Locally
