Determination of the Box-counting Fractal Dimension of Pore Distribution in Eggshell Based on Scanning Electron Microscopy Image Analysis
(0) The fractal characteristics of pore structures were investigated using duck eggshells as an object of study.The images of the sharp end, the equator and the blunt end of the eggshells were acquired by using scanning electronic microscope.The image processing operations were conducted for the preprocessing and the image converted into binary image.Then we developed programs based on the principle of changing megascopic degree and applied them to plot the lgN(5)~lg(5).The relationship between IgN(8)and /g(δ)maintained linearity over a range 2,64 pixels.Therefore, the fractal dimensions of pore distributions were obtained from the negative slope by regression analysis.The experimental results showed that the fractal feature of the pore in eggshells was remarkable.The analysis confirmed that the blunt end of the eggshell in the pore distributions was more obvious than the sharp end and the equator.
