摘　　要：探讨基于傅立叶谱分析法对棉绉织物进行绉效应评价的可行性和符合性。首先对棉绉织物纹理的二维图像进行傅立叶变换,对频谱图进行了沿半径方向的积分,通过二维图像的径向分布来分析纹理图像的起绉程度。结果表明:对于不同起绉程度棉绉织物的起绉图像,其谱密度分布中低频区域的分量也不同;起绉程度越严重,图像中所体现出的低频灰度区域越多,对应的低频谱成分也越多;另外,低频区域曲线所包含的面积,客观上也可反映起绉程度。采用以上方法进行棉绉织物绉效应的评价与主观评价相近。Feasibility and suitability of using Fourier spectrum analysing crepe effect of cotton crepe fabric were discussed. Fourier transform was used in two dimension images of cotton crepe fabrics texture, integral of spectrogram along radius were calculated, crepe degree of texture image was analysed through radial distribution of two dimension image. The result shows that for crepe image of cotton fabric with different crepe degree ,low-frequency component in spectrum density distribution is different. The more serious crepe degree, the larger low-frequency gray zone embodied in image ,the more low-frequency component. Moreover, area of low-frequency curve covering could reflect crepe degree objectively in certain degree. The above evaluations are approaching to subjective evaluations.
