Application of image processing on analyzing the structure of spatial-temporal pattern
Xiaohong Yang, Shuhua Liu · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2007
In this work, we present some practical methods for analyzing the structure of spatial-temporal patterns with Matlab, including "Fourier transform", "obtaining the sketch of the pattern", "obtaining the brightness distribution in the pattern", "filtering the noise in the pattern", and so on. The types of the patterns can be determined by obtaining the spatial frequency spectrum of the patterns using Fourier transform. To obtain the sketches of the patterns can make the measurement of pattern structure parameters easier and more accurately. To obtain the brightness distribution in the patterns can help us to analyze the physics mechanism of the pattern formation systems. To filter the noise in the patterns can make the pattern pictures more clearly. This work can provide a beneficial reference for researchers who study pattern dynamics in different systems.
