Paper Abstract

A method for two-dimensional pattern recognition, applicable to particle shape and size determination, is presented which employs fractal geometric analysis. Fractal contour transformation presents several advantages over spatial harmonic analysis: 1.preservation of translation, rotation, and scale invariance 2.reduced reliance upon high-frequency Fourier transform coefficients 3.improved signal-to-noise ratio of the fractal transform over the Fourier transform for surface feature discrinination. Coordinate transformation is evaluated with respect to its effect upon feature discrimination in polar-mapped multivariable contours. A variety of non-differentiable contours are analyzed. Results are presented in terms of correlation, signal-to-noise ration, and computational load.
