碩士 === 國立臺灣科技大學 === 機械工程系 === 90 === The advance of VLSI and DSP make the speed and functionalities of DSP greatly improved and the precision and real-time performance of system with complex function can be archived, so that we can use it to develop the intelligent mechanical system. The feature of wavelet transform not only makes time domain signal transformation to frequency domain signal but get the time domain property of that signal. The wavelet transform is very suit for the image processing. This thesis is devoted to develop a DSP-base image cognition system by using wavelet transform. It can apply to horizontal texture image which making by laser interferometer. So that we can use wavelet transform to get the defect of a horizontal texture image, and also get the degree of defect by using gray level co-occurrence matrix.
