# SuperPoint

[SuperPoint](https://huggingface.co/papers/1712.07629) is the result of self-supervised training of a fully-convolutional network for interest point detection and description. The model is able to detect interest points that are repeatable under homographic transformations and provide a descriptor for each point. Usage on it's own is limited, but it can be used as a feature extractor for other tasks such as homography estimation and image matching.

You can find all the original SuperPoint checkpoints under the [Magic Leap Community](https://huggingface.co/magic-leap-community) organization.

The example below demonstrates how to detect interest points in an image with the [AutoModel](/docs/transformers/pr_48314/en/model_doc/auto#transformers.AutoModel) class.

```python
import requests
import torch
from PIL import Image

from transformers import AutoImageProcessor, SuperPointForKeypointDetection

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)

processor = AutoImageProcessor.from_pretrained("magic-leap-community/superpoint")
model = SuperPointForKeypointDetection.from_pretrained("magic-leap-community/superpoint", device_map="auto")

inputs = processor(image, return_tensors="pt").to(model.device)
with torch.no_grad():
    outputs = model(**inputs)

# Post-process to get keypoints, scores, and descriptors
image_size = (image.height, image.width)
processed_outputs = processor.post_process_keypoint_detection(outputs, [image_size])
```

## Notes

- SuperPoint outputs a dynamic number of keypoints per image, which makes it suitable for tasks requiring variable-length feature representations.

    ```py
    from transformers import AutoImageProcessor, SuperPointForKeypointDetection
    import torch
    from PIL import Image
    import requests
    processor = AutoImageProcessor.from_pretrained("magic-leap-community/superpoint")
    model = SuperPointForKeypointDetection.from_pretrained("magic-leap-community/superpoint", device_map="auto")
    url_image_1 = "http://images.cocodataset.org/val2017/000000039769.jpg"
    image_1 = Image.open(requests.get(url_image_1, stream=True).raw)
    url_image_2 = "http://images.cocodataset.org/test-stuff2017/000000000568.jpg"
    image_2 = Image.open(requests.get(url_image_2, stream=True).raw)
    images = [image_1, image_2]
    inputs = processor(images, return_tensors="pt").to(model.device)
    # Example of handling dynamic keypoint output
    outputs = model(**inputs)
    keypoints = outputs.keypoints  # Shape varies per image
    scores = outputs.scores        # Confidence scores for each keypoint
    descriptors = outputs.descriptors  # 256-dimensional descriptors
    mask = outputs.mask # Value of 1 corresponds to a keypoint detection
    ```

- The model provides both keypoint coordinates and their corresponding descriptors (256-dimensional vectors) in a single forward pass.
- For batch processing with multiple images, you need to use the mask attribute to retrieve the respective information for each image. You can use the `post_process_keypoint_detection` from the `SuperPointImageProcessor` to retrieve the each image information.

    ```py
    # Batch processing example
    images = [image1, image2, image3]
    inputs = processor(images, return_tensors="pt").to(model.device)
    outputs = model(**inputs)
    image_sizes = [(img.height, img.width) for img in images]
    processed_outputs = processor.post_process_keypoint_detection(outputs, image_sizes)
    ```

- You can then print the keypoints on the image of your choice to visualize the result:

    ```py
    import matplotlib.pyplot as plt
    plt.axis("off")
    plt.imshow(image_1)
    plt.scatter(
        outputs[0]["keypoints"][:, 0],
        outputs[0]["keypoints"][:, 1],
        c=outputs[0]["scores"] * 100,
        s=outputs[0]["scores"] * 50,
        alpha=0.8
    )
    plt.savefig(f"output_image.png")
    ```

Configuration objects inherit from [PreTrainedConfig](/docs/transformers/pr_48314/en/main_classes/configuration#transformers.PreTrainedConfig) and can be used to control the model outputs. Read the
documentation from [PreTrainedConfig](/docs/transformers/pr_48314/en/main_classes/configuration#transformers.PreTrainedConfig) for more information.

Example:
```python
>>> from transformers import SuperPointConfig, SuperPointForKeypointDetection

>>> # Initializing a SuperPoint superpoint style configuration
>>> configuration = SuperPointConfig()
>>> # Initializing a model from the superpoint style configuration
>>> model = SuperPointForKeypointDetection(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config

SuperPoint model outputting keypoints and descriptors.

This model inherits from [PreTrainedModel](/docs/transformers/pr_48314/en/main_classes/model#transformers.PreTrainedModel). Check the superclass documentation for the generic methods the
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
etc.)

This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
and behavior.

#### forward[[transformers.SuperPointForKeypointDetection.forward]]

```python
forward(pixel_values: FloatTensor, labels: typing.Optional[torch.LongTensor] = None, output_hidden_states: bool | None = None, return_dict: bool | None = None, **kwargs)
```

[Source](https://github.com/huggingface/transformers/blob/vr_48314/src/transformers/models/superpoint/modeling_superpoint.py#L373)

**Parameters:**

pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)`) : The tensors corresponding to the input images. Pixel values can be obtained using [SuperPointImageProcessor](/docs/transformers/pr_48314/en/model_doc/superpoint#transformers.SuperPointImageProcessor). See `SuperPointImageProcessor.__call__()` for details (`processor_class` uses [SuperPointImageProcessor](/docs/transformers/pr_48314/en/model_doc/superpoint#transformers.SuperPointImageProcessor) for processing images).

labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) : Labels for computing the masked language modeling loss. Indices should either be in `[0, ..., config.vocab_size]` or -100 (see `input_ids` docstring). Tokens with indices set to `-100` are ignored (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`.

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](/docs/transformers/pr_48314/en/main_classes/output#transformers.utils.ModelOutput) instead of a plain tuple.

**Returns:** `SuperPointKeypointDescriptionOutput` or `tuple(torch.FloatTensor)`

A `SuperPointKeypointDescriptionOutput` or a tuple of
`torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various
elements depending on the configuration ([SuperPointConfig](/docs/transformers/pr_48314/en/model_doc/superpoint#transformers.SuperPointConfig)) and inputs.

The [SuperPointForKeypointDetection](/docs/transformers/pr_48314/en/model_doc/superpoint#transformers.SuperPointForKeypointDetection) 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.

- **loss** (`torch.FloatTensor` of shape `(1,)`, *optional*) -- Loss computed during training.
- **keypoints** (`torch.FloatTensor` of shape `(batch_size, num_keypoints, 2)`) -- Relative (x, y) coordinates of predicted keypoints in a given image.
- **scores** (`torch.FloatTensor` of shape `(batch_size, num_keypoints)`) -- Scores of predicted keypoints.
- **descriptors** (`torch.FloatTensor` of shape `(batch_size, num_keypoints, descriptor_size)`) -- Descriptors of predicted keypoints.
- **mask** (`torch.BoolTensor` of shape `(batch_size, num_keypoints)`) -- Mask indicating which values in keypoints, scores and descriptors are keypoint information.
- **hidden_states** (`tuple(torch.FloatTensor)`, *optional*, returned when `output_hidden_states=True` is passed or
  when `config.output_hidden_states=True`) -- Tuple of `torch.FloatTensor` (one for the output of the embeddings, if the model has an embedding layer, +
  one for the output of each stage) of shape `(batch_size, sequence_length, hidden_size)`. Hidden-states
  (also called feature maps) of the model at the output of each stage.
