Previously we featured visualizations of selected paintings by Impressionist artists created by Megan O'Rourke in my undergraduate class at UCSD (Winter 2012). One visualization compared works of artists using multiple image plots; the second used color histograms to show the same data in a different way.
Here is Megan's final class project which extends her investigation into new areas: comparing how different artists represented faces using image averaging, and visualizing evolution of their paintings over time in relation to brightness, saturation and hue.
To measure image properties used for visualizations, Megan used ImageMeasure macro which we distributed as part of our free ImagePlot software.
