 \n\nYou can use OWL-ViT to query images with text descriptions of any object. 
 To use it, simply upload an image and enter comma separated text descriptions of objects you want to query the image for. You
-can also use the score threshold slider to set a threshold to filter out low probability predictions.

+\n\nOWL-ViT is trained on text templates,
