Multifractal analysis and authentication of Jackson Pollock paintings

Recent work has shown that the mathematics of fractal geometry can be used to provide a quantitative signature for the drip paintings of Jackson Pollock. In this paper we discuss the calculation of a related quantity, the "entropy dimension" and discuss the possibility of its use a measure or signature for Pollock's work. We furthermore raise the question of the robustness or stability of the fractal measurements with respect to variables like mode of capture, digital resolution, and digital representation and include the results of a small experiment in the step of color layer extraction.
