Photographic dataset of playing cards

T. Helenius, S. Kaupinmäki, D. Villacis, and S. Siltanen


This is an open-access photographic dataset of playing cards. The data can be freely used for scientific purposes with appropriate references to the data. The idea is to have sets of identical photos with varying image noise.

Documentation in arXiv:
https://arxiv.org/abs/1701.07354

Files:
import_data.m
main.m
image_stretchlim.m
extract_phantom.m
image_adjust_spline.m
histogram_matching.m
write_tif.m
TVL1denoise.m
make_nabla.m

These Matlab routines take as input the original photographs and output the corrected images, as seen below.

Separate files:

  Original

im_clean.tif
im_noise1.tif
im_noise2.tif
im_noise3.tif
  Corrected

im_clean.tif
corrected_im_noise1.tif
corrected_im_noise2.tif
corrected_im_noise3.tif

Example usage in Matlab:
im = imread('im_clean.tif');
im = double(im); % Converting to floating point data

Photographic dataset of random peppercorns

T. Helenius and S. Siltanen


This is an open-access photographic dataset of randomly distributed peppercorns. The data can be freely used for scientific purposes with appropriate references to the data and to the documentation of the data in arXiv. The idea is to have sets of different but statistically similar images.

Documentation in arXiv:

Separate files:
Peppercorn_1.tif
Peppercorn_2.tif
Peppercorn_3.tif
Peppercorn_4.tif
Peppercorn_5.tif
Peppercorn_6.tif
Peppercorn_7.tif
Peppercorn_8.tif
Peppercorn_9.tif
Peppercorn_10.tif

Example usage in Matlab:
im = imread('Peppercorn_1.tif');
im = double(im); % Converting to floating point data
