QR-Code dataset, with colour embed inside
<p>This data-set is used in research of color difference recognition in unsupervised learning.</p> <p>Each image in this dataset has three colour areas embed inside a QR-Code. Each QR-Code has white area (3x3 cells), black area (3x3 cells) and colour area (3x3 cells).</p> <ul> <li><em>a standard office laserjet has been used to print materials, </em><em>printing has also been done for standard office A4-paper. </em></li> <li><em>The images </em><em>were captured with an iPhone 7, an iPhone 11 Pro and a Nokia TA-1032, with their </em><em>built-in camera applications. All of the camera applications used were set to use </em><em>automatic settings for white balance and other settings. The purpose was to mimic t</em><em>he consumer taking a photo.</em></li> </ul> <p>Package contains folders which have image files. In each folder there are QR-Codes with different colour areas, naming convention of folder is:<br><br>-Used CMYK intesity + used colours<br>-For example:<br>-- folder "60M" -> 0% C , 60%M, 0%Y, 0%K<br>-- folder "20CY" -> 20% C , 0%M, 20%Y, 0%K</p>

The QR code of SNARE proteins
<p>The raw data belong to a study in which we studied the geometric pattern of SNARE complexes. These proteins form stable four-helix bundles from four different helices. Some of the hydrophobic coiled-coil layers are asymmetric. We found that there is a matching pattern in the core of the complex that dictates the position of the four fundamental SNARE types in the bundle. The raw data include biochemical analyses, molecular dynamics simulations and other calculations. In addition, the data for the respective figures are included in the package. </p>
QR-codes with colour embed inside
<p>This repository contains QR-Code which have special colour areas embed inside them. Different colour areas are placed in folders. Folder name describes the colour represented in the image, for example 5C means that there is 5% cyan colour area and 10CY means 10% cyan, 10% yellow</p>
