Color recognition data set

This data-set is used in research of color difference recognition. <br> Dataset contains images extracted from functional markers, in these images there are differect QR-Code cells presented.<br> Extracted area has total of 5 rows, where functional part of the marker, sensor ink, is on rows 3 and 4. - Black cells illustrate QR-Codes black cells (binary 1)<br> - White (or no color) cells illustrate QR-Codes white cells (binary 0)<br> - Colored cells (only on rows 3 &amp; 4) appear in different intensity and they are considered as white cells (binary 0) intensity and color of colored cells vary as defined in filename. Image have been capture with iPhone 8 in varying conditions. Filename defines following, underscore (_) is used as separator - Filename always starts with text "sensor"<br> - QR-code size in cells<br> - Capturing distance in centimeters (if not measured then "X")<br> - Color intensity in percentage and color channel (RGB or CMYK), for example 10G = 10% in Green channel and 20CM = 20 in Cyan and Magenta<br> - Ambient light in LUX (if not measured then "X")
