OWL-ViT

##
Overview

The OWL-ViT (short for Vision Transformer for Open-World Localization) was proposed in Simple Open-Vocabulary Object Detection with Vision Transformers by Matthias Minderer, Alexey Gritsenko, Austin Stone, Maxim Neumann, Dirk Weissenborn, Alexey Dosovitskiy, Aravindh Mahendran, Anurag Arnab, Mostafa Dehghani, Zhuoran Shen, Xiao Wang, Xiaohua Zhai, Thomas Kipf, and Neil Houlsby. OWL-ViT is an open-vocabulary object detection network trained on a variety of (image, text) pairs. It can be used to query an image with one or multiple text queries to search for and detect target objects described in text.

The abstract from the paper is the following:

Combining simple architectures with large-scale pre-training has led to massive improvements in image classification. For object detection, pre-training and scaling approaches are less well established, especially in the long-tailed and open-vocabulary setting, where training data is relatively scarce. In this paper, we propose a strong recipe for transferring image-text models to open-vocabulary object detection. We use a standard Vision Transformer architecture with minimal modifications, contrastive image-text pre-training, and end-to-end detection fine-tuning. Our analysis of the scaling properties of this setup shows that increasing image-level pre-training and model size yield consistent improvements on the downstream detection task. We provide the adaptation strategies and regularizations needed to attain very strong performance on zero-shot text-conditioned and one-shot image-conditioned object detection. Code and models are available on GitHub.

Usage tips

OWL-ViT is a zero-shot text-conditioned object detection model. OWL-ViT uses CLIP as its multi-modal backbone, with a ViT-like Transformer to get visual features and a causal language model to get the text features. To use CLIP for detection, OWL-ViT removes the final token pooling layer of the vision model and attaches a lightweight classification and box head to each transformer output token. Open-vocabulary classification is enabled by replacing the fixed classification layer weights with the class-name embeddings obtained from the text model. The authors first train CLIP from scratch and fine-tune it end-to-end with the classification and box heads on standard detection datasets using a bipartite matching loss. One or multiple text queries per image can be used to perform zero-shot text-conditioned object detection.

OwlViTImageProcessor can be used to resize (or rescale) and normalize images for the model and CLIPTokenizer is used to encode the text. OwlViTProcessor wraps OwlViTImageProcessor and CLIPTokenizer into a single instance to both encode the text and prepare the images. The following example shows how to perform object detection using OwlViTProcessor and OwlViTForObjectDetection.

    >>> import requests
    >>> from PIL import Image
    >>> import torch

    >>> from transformers import OwlViTProcessor, OwlViTForObjectDetection

    >>> processor = OwlViTProcessor.from_pretrained("google/owlvit-base-patch32")
    >>> model = OwlViTForObjectDetection.from_pretrained("google/owlvit-base-patch32")

    >>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
    >>> image = Image.open(requests.get(url, stream=True).raw)
    >>> texts = [["a photo of a cat", "a photo of a dog"]]
    >>> inputs = processor(text=texts, images=image, return_tensors="pt")
    >>> outputs = model(**inputs)

    >>> # Target image sizes (height, width) to rescale box predictions [batch_size, 2]
    >>> target_sizes = torch.Tensor([image.size[::-1]])
    >>> # Convert outputs (bounding boxes and class logits) to Pascal VOC format (xmin, ymin, xmax, ymax)
    >>> results = processor.post_process_object_detection(outputs=outputs, target_sizes=target_sizes, threshold=0.1)
    >>> i = 0  # Retrieve predictions for the first image for the corresponding text queries
    >>> text = texts[i]
    >>> boxes, scores, labels = results[i]["boxes"], results[i]["scores"], results[i]["labels"]
    >>> for box, score, label in zip(boxes, scores, labels):
    ...     box = [round(i, 2) for i in box.tolist()]
    ...     print(f"Detected {text[label]} with confidence {round(score.item(), 3)} at location {box}")
    Detected a photo of a cat with confidence 0.707 at location [324.97, 20.44, 640.58, 373.29]
    Detected a photo of a cat with confidence 0.717 at location [1.46, 55.26, 315.55, 472.17]

- image_embeds (`torch.FloatTensor` of shape `(batch_size, output_dim`) — The image embeddings obtained by applying the projection layer to the pooled output of OwlViTVisionModel.
- text_model_output (Tuple`BaseModelOutputWithPooling`) — The output of the OwlViTTextModel.
- vision_model_output (`BaseModelOutputWithPooling`) — The output of the OwlViTVisionModel.

The OwlViTModel forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

text_features (`torch.FloatTensor` of shape `(batch_size, output_dim`)

Parameters

- input_ids (`torch.LongTensor` of shape `(batch_size * num_max_text_queries, sequence_length)`) — Indices of input sequence tokens in the vocabulary. Indices can be obtained using AutoTokenizer. See PreTrainedTokenizer.encode() and PreTrainedTokenizer.call() for details. What are input IDs?
- attention_mask (`torch.Tensor` of shape `(batch_size, num_max_text_queries, sequence_length)`, optional) — Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
  - 1 for tokens that are not masked,
  - 0 for tokens that are masked. What are attention masks?
- output_attentions (`bool`, optional) — Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail.
- output_hidden_states (`bool`, optional) — Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for more detail.
- return_dict (`bool`, optional) — Whether or not to return a ModelOutput instead of a plain tuple.

Returns

text_features (`torch.FloatTensor` of shape `(batch_size, output_dim`)

The text embeddings obtained by applying the projection layer to the pooled output of OwlViTTextModel.

The OwlViTModel forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Examples:

    >>> from transformers import AutoProcessor, OwlViTModel

    >>> model = OwlViTModel.from_pretrained("google/owlvit-base-patch32")
    >>> processor = AutoProcessor.from_pretrained("google/owlvit-base-patch32")
    >>> inputs = processor(
    ...     text=[["a photo of a cat", "a photo of a dog"], ["photo of a astranaut"]], return_tensors="pt"
