+# SuperGlue
+
+The SuperGlue model was proposed
+in [SuperGlue: Learning Feature Matching with Graph Neural Networks](https://arxiv.org/abs/1911.11763) by Paul-Edouard Sarlin, Daniel
+DeTone, Tomasz Malisiewicz and Andrew Rabinovich.
+
+This model consists of matching two sets of interest points detected in an image. Paired with the 
+[SuperPoint model](https://huggingface.co/magic-leap-community/superpoint), it can be used to match two images and 
+estimate the pose between them. This model is useful for tasks such as image matching, homography estimation, etc.
+
+The abstract from the paper is the following:
+
+*This paper introduces SuperGlue, a neural network that matches two sets of local features by jointly finding correspondences 
+and rejecting non-matchable points. Assignments are estimated by solving a differentiable optimal transport problem, whose costs 
+are predicted by a graph neural network. We introduce a flexible context aggregation mechanism based on attention, enabling 
+SuperGlue to reason about the underlying 3D scene and feature assignments jointly. Compared to traditional, hand-designed heuristics, 
+our technique learns priors over geometric transformations and regularities of the 3D world through end-to-end training from image 
+pairs. SuperGlue outperforms other learned approaches and achieves state-of-the-art results on the task of pose estimation in 
+challenging real-world indoor and outdoor environments. The proposed method performs matching in real-time on a modern GPU and 
+can be readily integrated into modern SfM or SLAM systems. The code and trained weights are publicly available at this [URL](https://github.com/magicleap/SuperGluePretrainedNetwork).*

+## Model Details
+
+### Model Description
+
+SuperGlue is a neural network that matches two sets of local features by jointly finding correspondences and rejecting non-matchable points. 
+It introduces a flexible context aggregation mechanism based on attention, enabling it to reason about the underlying 3D scene and feature 
+assignments. The architecture consists of two main components: the Attentional Graph Neural Network and the Optimal Matching Layer.

+
+The Attentional Graph Neural Network uses a Keypoint Encoder to map keypoint positions and visual descriptors. 
+It employs self- and cross-attention layers to create powerful representations. The Optimal Matching Layer creates a 
+score matrix, augments it with dustbins, and finds the optimal partial assignment using the Sinkhorn algorithm.

+
+### Direct Use
+
+SuperGlue is designed for feature matching and pose estimation tasks in computer vision. It can be applied to a variety of multiple-view 
+geometry problems and can handle challenging real-world indoor and outdoor environments. However, it may not perform well on tasks that 
+require different types of visual understanding, such as object detection or image classification.
+
+
+## How to Get Started with the Model
+
+
+Here is a quick example of using the model. Since this model is an image matching model, it requires pairs of images to be matched:
+
+```python
+from transformers import AutoImageProcessor, AutoModel
+import torch
+from PIL import Image
+import requests
+url = "https://raw.githubusercontent.com/magicleap/SuperGluePretrainedNetwork/refs/heads/master/assets/phototourism_sample_images/united_states_capitol_98169888_3347710852.jpg"
+im1 = Image.open(requests.get(url, stream=True).raw)
+url = "https://raw.githubusercontent.com/magicleap/SuperGluePretrainedNetwork/refs/heads/master/assets/phototourism_sample_images/united_states_capitol_26757027_6717084061.jpg"
+im2 = Image.open(requests.get(url, stream=True).raw)
+images = [im1, im2]
+processor = AutoImageProcessor.from_pretrained("stevenbucaille/superglue_outdoor")
+model = AutoModel.from_pretrained("stevenbucaille/superglue_outdoor")
+inputs = processor(images, return_tensors="pt")
+outputs = model(**inputs)
+```
+
+The outputs contain the list of keypoints detected by the keypoint detector as well as the list of matches with their corresponding matching scores.
+Due to the nature of SuperGlue, to output a dynamic number of matches, you will need to use the mask attribute to retrieve the respective information:
+
+```python
+from transformers import AutoImageProcessor, AutoModel
+import torch
+from PIL import Image
+import requests
+url_image_1 = "https://raw.githubusercontent.com/magicleap/SuperGluePretrainedNetwork/refs/heads/master/assets/phototourism_sample_images/united_states_capitol_98169888_3347710852.jpg"
+image_1 = Image.open(requests.get(url_image_1, stream=True).raw)
+url_image_2 = "https://raw.githubusercontent.com/magicleap/SuperGluePretrainedNetwork/refs/heads/master/assets/phototourism_sample_images/united_states_capitol_26757027_6717084061.jpg"
+image_2 = Image.open(requests.get(url_image_2, stream=True).raw)
+images = [image_1, image_2]
+processor = AutoImageProcessor.from_pretrained("stevenbucaille/superglue_indoor")
+model = AutoModel.from_pretrained("stevenbucaille/superglue_indoor")
+inputs = processor(images, return_tensors="pt")
+with torch.no_grad():
+    outputs = model(**inputs)
+# Get the respective image masks 
+image0_mask, image1_mask = outputs_mask[0]
+image0_indices = torch.nonzero(image0_mask).squeeze()
+image1_indices = torch.nonzero(image1_mask).squeeze()
+image0_matches = outputs.matches[0, 0][image0_indices]
+image1_matches = outputs.matches[0, 1][image1_indices]
+image0_matching_scores = outputs.matching_scores[0, 0][image0_indices]
+image1_matching_scores = outputs.matching_scores[0, 1][image1_indices]
+```
+
+You can use the `post_process_keypoint_matching` method from the `SuperGlueImageProcessor` to get the keypoints and matches in a more readable format:
+```python
+image_sizes = [(image.height, image.width) for image in images]
+outputs = processor.post_process_keypoint_matching(outputs, image_sizes, threshold=0.2)
+for i, output in enumerate(outputs):
+    print("For the image pair", i)
+    for keypoint0, keypoint1, matching_score in zip(output["keypoints0"], output["keypoints1"],
+                                                    output["matching_scores"]):
+        print(
+            f"Keypoint at coordinate {keypoint0.numpy()} in the first image matches with keypoint at coordinate {keypoint1.numpy()} in the second image with a score of {matching_score}."
+        )
+```
+
+From the outputs, you can visualize the matches between the two images using the following code:
+```python
+import matplotlib.pyplot as plt
+import numpy as np
+# Create side by side image
+merged_image = np.zeros((max(image1.height, image2.height), image1.width + image2.width, 3))
+merged_image[: image1.height, : image1.width] = np.array(image1) / 255.0
+merged_image[: image2.height, image1.width :] = np.array(image2) / 255.0
+plt.imshow(merged_image)
+plt.axis("off")
+# Retrieve the keypoints and matches
+output = outputs[0]
+keypoints0 = output["keypoints0"]
+keypoints1 = output["keypoints1"]
+matching_scores = output["matching_scores"]
+keypoints0_x, keypoints0_y = keypoints0[:, 0].numpy(), keypoints0[:, 1].numpy()
+keypoints1_x, keypoints1_y = keypoints1[:, 0].numpy(), keypoints1[:, 1].numpy()
+# Plot the matches
+for keypoint0_x, keypoint0_y, keypoint1_x, keypoint1_y, matching_score in zip(
+        keypoints0_x, keypoints0_y, keypoints1_x, keypoints1_y, matching_scores
+):
+    plt.plot(
+        [keypoint0_x, keypoint1_x + image1.width],
+        [keypoint0_y, keypoint1_y],
+        color=plt.get_cmap("RdYlGn")(matching_score.item()),
+        alpha=0.9,
+        linewidth=0.5,
+    )
+    plt.scatter(keypoint0_x, keypoint0_y, c="black", s=2)
+    plt.scatter(keypoint1_x + image1.width, keypoint1_y, c="black", s=2)
+# Save the plot
+plt.savefig("matched_image.png", dpi=300, bbox_inches='tight')
+plt.close()
+```

+
+## Training Details
+
+### Training Data
+
+SuperGlue is trained on large annotated datasets for pose estimation, enabling it to learn priors for pose estimation and reason about the 3D scene.
+The training data consists of image pairs with ground truth correspondences and unmatched keypoints derived from ground truth poses and depth maps.
+
+### Training Procedure 
+
+SuperGlue is trained in a supervised manner using ground truth matches and unmatched keypoints. The loss function maximizes 
+the negative log-likelihood of the assignment matrix, aiming to simultaneously maximize precision and recall.
+
+#### Training Hyperparameters
+
+- **Training regime:** fp32
+
+#### Speeds, Sizes, Times
+
+SuperGlue is designed to be efficient and runs in real-time on a modern GPU. A forward pass takes approximately 69 milliseconds (15 FPS) for an indoor image pair. 
+The model has 12 million parameters, making it relatively compact compared to some other deep learning models.
+The inference speed of SuperGlue is suitable for real-time applications and can be readily integrated into 
+modern Simultaneous Localization and Mapping (SLAM) or Structure-from-Motion (SfM) systems.
