- Abstract
- Shot-, grit-, and sand-blasted Keane-Tator comparator leaves were thermographically imaged and their fractal dimension computed. It was found that imaging a heated roughened surface with a thermographic camera provides a good delineation of the peak-to-valley heights of the structures on the surface and that, in general, the coimputed fractal dimension increased with an increase in profile depth and an increase in the concentration of the crater-like structures. It was also shown that fractals adequately describe an abraded surface in that the computed fractal dimension can be used as input into a simulation model from which most of the perceptually relevant shape structures on the originally imaged surface can be reconstructed.
