Fractal-D, Fractal Dimension EstimationThe fractal dimension, D, of the outline of an object provides information about its complexity that goes beyond that available through ordinary Euclidean methods. Fractal-D introduces the user to the potential of fractal analysis by providing a means by which this statistic can easily be estimated for two-dimensional data sets. The estimation procedure, commonly referred to as the “divider” method, and the results of the analysis are both displayed graphically. Fractal-D accepts user-supplied outlines. The final screen in a typical analysis shows the outline of the object being analyzed on the left and a plot of log-lengths versus log-step sizes on the right. The slope of the regression line is used to estimate the fractal dimension. The program can also generate simulated outlines that can be analyzed in a similar way. Fractal-D supports MorphoSys contour files, both interactive and batch mode operation. It comes complete with sample data files and a manual that contains user information, suggested exercises (using sample files), and selected references to applications of fractal geometry in the physical and biological sciences. Requirements: PC compatible, DOS 3.3+, 256K+ RAM, and a graphics adapter (Hercules, CGA, MCGA, EGA, and VGA are supported). Cost: $75.00. Ten-user site license $295.00 Note: while this is an old DOS program, it is still listed because some find it useful. |
