Longitudinal Shoe Study: Vinyl Print Photos
dataset
posted on 2019-11-26, 15:11 authored by Susan VanderplasSusan Vanderplas, Alicia Carriquiry, James Kruse, Guillermo Basulto-Elias, Stacy RenfroImages of 160 shoe prints (“Nike Winflo 4” or “Adidas Seeley”; 4 sizes each) made on vinyl plank flooring (wood patterned) using fingerprint powder, with associated measurements and data about shoe wear, surfaces, and wearers.
Each pair of shoes was worn for at least 10,000 steps per week over a 6-month period, with multiple measurements of the shoe soles taken initially and during three check-in periods spaced at approximately 5 week intervals.
The images are accompanied by 3 CSV files describing the shoes, visit (information collected from surveys along with the shoes), and individual images. The codebooks contain descriptions of the variables in each of the CSV files as well as a more extensive description of the Method_Image_Replicate coding outlined in the README.
These files are intended to provide patterns similar to those which might be found at a crime-scene; they can be used for testing algorithms on images with real-world problems (background patterns, lighting constraints) as well as for white and black-box studies with forensic examiners.
