摘　　要：对傅立叶变换在纺织图像滤波、无纺布中纤维取向度检测、以及织物结构参数测量等方面的应用进行了研究和分析,研究的结果表明:傅立叶变换技术是非常有效的.The Fast Fourier Transform (FFT) plays a very important role in image processing. Pprocedures for applying FFT techniques in textile testing, which include image filtering, the measurement of fiber orientation in nonwovens and the measurement of structural characteristics of woven fabrics are discussed. The results show that the FFT techniques is an efficient and reliable method.
