Wavelet analysis of ceramic surface images as a method for measuring the size of structural elements

Abstract
The expediency of applying the wavelet analysis method to visualize and measure structural elements on the surface of ceramic samples is shown. The experimental results of image processing of the surface of samples made of kaolin clay using wavelet analysis are presented. Examples of applying the wavelet transform to the study of model images with simple geometry and precisely known sizes of structural elements of the “checkerboard” type are considered. A relation is proposed that relates the particle size to the scale parameter of the wavelet spectrum. A simple and modern method makes it possible to record and quantify the structural changes occurring in highly dispersed ceramic samples under the influence of a microwave field. It was found that on the surface of ceramic samples processed in a microwave field, the sizes of structural elements (particles) are reduced by an average of 20%; the surface itself becomes more uniform. This effect is extremely promising for the development of technology for producing finely dispersed ceramic materials.
