碩士 === 國立臺灣科技大學 === 電機工程系 === 92 === Abstract Textured image research is a topic worth many effort. In this issue, there is generally no widely accepted way to describe a textured image at present. The usual way has to depend on the property of texture and the domain of the application. In this research, we try to analyze a type of artificially generated texture images. Based on the feature of texture element combination we use hierarchical modeling and further improve the hierarchical modeling using the projective hierarchical modeling. This model could describe the texture more efficiency. The regular texture image is very suitable to analyze in frequency way since texture element is in fixed placement and shows strong periodicity. We use the Fourier transform to analyze the frequency content of a texture image. We can get the frequency distribution in each direction and get the period of the texture. We can also get the displacement of the texture image by observe the variation of phase. At the end of the research we show that the period calculated by observing the spectrum is very close to the period of that is actually measured.
