Dataset Card for MIMIC


 Motivation
 1. For what purpose was the dataset created? Was there a specific task in mind? Was there a specific gap that needed to be filled? Please provide a description. 

The contributions of our dataset to the vision community are listed below: (1) We release a pretraining dataset of 3.1M image pairs from diverse sets of videos, 3D scans, street views, and … for downstream dense prediction tasks. (2) The dataset can be scaled quickly because of the proposed data curation strategy. This strategy doesn't need any annotation except the images themselves.

2. Who created the dataset (e.g., which team, research group) and on behalf of which entity (e.g., company, institution, organization)?

Composition
 1. What do the instances that comprise the dataset represent (e.g., documents, photos, people, countries)? Are there multiple types of instances (e.g., movies, users, and ratings; people and interactions between them; nodes and edges)? Please provide a description. 

All of the instances in the dataset are images. Common themes of the images include street locations, objects, indoor scenes, and frozen people from the Mannequin challenge. From each scene or object, pairs of images have at least 50% co-visibility.


2. How many instances are there in total (of each type, if appropriate)? 
There are 3.1 million image pairs. (6.2 images in total )



 3. Does the dataset contain all possible instances or is it a sample (not necessarily random) of instances from a larger set? If the dataset is a sample, then what is the larger set? Is the sample representative of the larger set (e.g., geographic coverage)? If so, please describe how this representativeness was validated/verified. If it is not representative of the larger set, please describe why not (e.g., to cover a more diverse range of instances, because instances were withheld or unavailable).

 The dataset contains all instances licensed. We sampled our image pairs from publicly licensed datasets.

4. What data does each instance consist of? “Raw” data (e.g., unprocessed text or images) or features? In either case, please provide a description. 

Instances are images resized to 224 x 224.

5. Is there a label or target associated with each instance? If so, please provide a description. 
There are no labels associated with each instance. However, we provide a dictionary of matching patches of each pair with that pair of images.


 6. Is any information missing from individual instances? If so, please provide a description, explaining why this information is missing (e.g., because it was unavailable). 

No, it isn't.

7. Are relationships between individual instances made explicit (e.g., users’ movie ratings, social network links)? If so, please describe how these relationships are made explicit. No, there are no known relationships between instances in the dataset.

Yes, in the csv file with all file paths, there is a metadata column that shows which original dataset is this image pair from. Also, each folder name in each dataset shows the name of the video/3d scene which subfolders with image pairs are created from.

 8. Are there any errors, sources of noise, or redundancies in the dataset? If so, please provide a description. 

Matching patches and overlap measurements are noisy because of the approximate matching algorithm, but this noise level in a large dataset is okay for pretraining.



 9. Is the dataset self-contained, or does it link to or otherwise rely on external resources (e.g., websites, tweets, other datasets)? If it links to or relies on external resources, a) are there guarantees that they will exist, and remain constant, over time; b) are there official archival versions of the complete dataset (i.e., including the external resources as they existed at the time the dataset was created); c) are there any restrictions (e.g., licenses, fees) associated with any of the external resources that might apply to a dataset consumer? Please provide descriptions of all external resources and any restrictions associated with them, as well as links or other access points, as appropriate.
 
The dataset is self-contained. 

10. Does the dataset contain data that might be considered confidential (e.g., data that is protected by legal privilege or by doctor-patient confidentiality, data that includes the content of individuals’ non-public communications)? If so, please provide a description.
 No. 

11. Does the dataset contain data that, if viewed directly, might be offensive, insulting, threatening, or might otherwise cause anxiety?
No, we are using all released public datasets.


12. Does the dataset identify any subpopulations (e.g., by age, gender)? If so, please describe how these subpopulations are identified and provide a description of their respective distributions within the dataset. 
The dataset has people engaging in the Mannequin challenge from all subpopulations.

13. Is it possible to identify individuals (i.e., one or more natural persons), either directly or indirectly (i.e., in combination with other data) from the dataset? If so, please describe how. 
Yes, we collected images of people engaging in the mannequin challenge from a public dataset.

14. Does the dataset contain data that might be considered sensitive in any way (e.g., data that reveals race or ethnic origins, sexual orientations, religious beliefs, political opinions or union memberships, or locations; financial or health data; biometric or genetic data; forms of government identification, such as social security numbers; criminal history)? If so, please provide a description. 
This dataset does not blur People’s faces, so it may reveal race. However, images with people were collected from a publicly available Mannequin dataset.

15. Any other comments? No.

 Collection Process 
1. How was the data associated with each instance acquired? Was the data directly observable (e.g., raw text, movie ratings), reported by subjects (e.g., survey responses), or indirectly inferred/derived from other data (e.g., part-of-speech tags, model-based guesses for age or language)? If the data was reported by subjects or indirectly inferred/derived from other data, was the data validated/verified? If so, please describe how.

It is indirectly inferred/derived from other public datasets like videos and 3D scans.


 2. What mechanisms or procedures were used to collect the data (e.g., hardware apparatuses or sensors, manual human curation, software programs, software APIs)? How were these mechanisms or procedures validated? 
The images in the dataset are extracted from publicly licensed datasets. 

 3. If the dataset is a sample from a larger set, what was the sampling strategy (e.g., deterministic, probabilistic with specific sampling probabilities)? 
We sampled pairs of images from different scenes (videos/3D scans) of public datasets with the condition of having 50 to 75% co-visibility.

 4. Who was involved in the data collection process (e.g., students, crowdworkers, contractors) and how were they compensated (e.g., how much were crowdworkers paid)? 
The authors only.



5. Over what timeframe was the data collected? Does this timeframe match the creation timeframe of the data associated with the instances (e.g., recent crawl of old news articles)? If not, please describe the timeframe in which the data associated with the instances was created. 

The public imaging datasets that we used vary in their date taken over a wide range of years up to 2022.
