DESCRIPTION:
Reddit photoshop battles (https://www.reddit.com/r/photoshopbattles/) is an online community that holds competitions to see who can generate the most amusing, relevant, or creative edited versions of original photos using tools such as Photoshop or GIMP.
Digital Image Provenance is the task of finding related and modified versions of an image and describing their relationships to an image in question (see [1]). The relationship between a set of images can be represented as a graph, where nodes represent images and edges represent the relationships (if any) between them. Image Provenance is an extension of Image Phylogeny [2].
Because contributors to the Reddit Photoshop battles often piggyback off of each other's work, their iterative edits to an original image provide perfect example cases for Image Provenance and Phylogeny related tasks.
OVERVIEW:
Each provenance case is inferred using timestamps and parent-child relationships from the comment threads in which the images are posted. Each graph has a root node that is the original image provided for the battle. See Figure 1.
REQUIREMENTS:
Python2.7
urllib2
urlparse
USAGE:
JSON representations of each photoshop battle are located in the 'Datasets' folder. Currently, we provide only the cases used in [1], located in the 'Datasets/TIP2018' folder. Newer and larger version of the dataset will be available shortly.
To generate the dataset, run:
python2 DownloadRedditDataset.py <json folder> -outputDir <output folder>
This will build a new folder structure located at the specified location, in which each photoshop battle case will be given a folder filled with its relevant images.
To Visualize the photoshop graph structures using Cytoscape.js (http://js.cytoscape.org/):
DSET=Datasets/TIP2018/
python Visualize/GenerateGraphVisuals.py $DSET #Generate interactive HTML files at $DSET/Visuals
python Visualize/StartVisServer.py $DSET #Start serving images to the javascript graphs
DISCLAIMER:
While this dataset has been cleaned and scrubbed by hand, we provide no all content provided in dataset JSON files is downloaded at your own risk, and could contain not-safe-for-work material.
Not all images provided by dataset JSON files are openly licensed, please get creator's permission for use before utilizing this data.
JSON STRUCTURE
Each graph case has a JSON file that describes its structure. the json format is as follows:
