OWL-ViT
### Feature request

Dear all,

It looks like [OWL-ViT](https://huggingface.co/docs/transformers/model_doc/owlvit) doesn't support image conditioned detection.

### Motivation

 Image conditioned detection is the most appealing feature of this model

### Your contribution

No, just pointing this out. Thanks
