Pattern Recognition and Quantitative Characterization of Surface Shape of Microcapsulized Pigment Particles

Abstract

Abstract: Microcapsulized particles of ultramarine pigment were prepared, then theiracidresistant colour differences (ΔE) were determined and their images were processed as well asthe patterns were recognized with a computer, so that they were quantitatively characterizedvia the study of the surface fractional dimensionality(D).The results showed that the largerthe Dvalue of ultramarine particles, the less the ΔEof them.
