Fractal dimensions from pixels of 2-D video display of complex system

Just wanted to capture this -- not sure if I completely understand it.

It is possible to determine the fractal dimension of a 2-D projection of a complex system by counting the number of pixels (i.e., boxes of side epsilon) for ever-decreasing values of epsilon, and plotting the results on a log-log plot.  The result should be a straight line and the slope is the fractal dimension of the system.
