Extract:

3 Colorimetric analysis

Disposing of a colour-calibrated digital image representing the painting, we project every pixel of the image to its corresponding position in the 3-dimensional CIELAB space, thus obtaining a cloud of points representing all the colours used in the painting, the colour distribution. We perform a segmentation of the CIELAB space into different regions, such as light and dark colours, pastels and saturated colours etc. This segmentation in CIELAB space also provides a segmentation of the painting itself. We can then perform a colorimetric analysis of the resulting regions separately, and extract several properties, such as the precision of the nuances, colour harmonies, principal colours etc. We can also perform statistical analyses of the colour distributions.
