The idea is to have sets of different but statistically similar images. The images show randomly distributed peppercorns. The dataset consists of ten high-resolution black and white images of peppercorn in TIFF file format. Documentation of the dataset is available at arxiv.org/abs/1603.01046. See also www.fips.fi/photographic_dataset.php. Example usage in Matlab: im = imread('Peppercorn_1.tif'); im = double(im); % Converting to floating point data The data is collected at the Industrial Mathematics Laboratory of the Department of Mathematics and Statistics of University of Helsinki.Openphotographyimage processingpeppercorndataset
