This paper brings forward a approach for textile flaw automatic detection based on optimal Gabor filters. At first the niche genetic algorithm is employed to attain the parameters of the optimal Gabor filters and segmentation threshold based on the feature of the unflawed textile,and then apply the optimal Gabor filter and threshold on the fabric image to achieve the resnlts.

为了对织物缺陷进行快速准确的自动检测，建立了一种基于Gabor滤波器的织物缺陷自动检测方法，即首先根据无缺陷织物的结构特征，应用小生境遗传算法寻找最优的Gabor滤波器参数和分割阈值；然后将待检图像通过滤波和分割来得到检测结果，同时根据响应矩阵的极小值点来计算缺陷的形状特征。

Based on this requirement, this paper introduced steerable filters: generated a pair of even and odd filtered images by convoluting a quadrature pair of steerable filters with a source image, and then through continuously varying their phases over time, it gave the vision of an object in motion without changing its position. created the animation conveniently in this way.

基于这种需求，将定向滤波引入到非真实感动画中：利用一对正交的定向滤波核与源图像进行卷积运算，产生一对奇偶滤波图像，并通过不断改变其相位得到一系列运动的图像，使图像内的物体在实际位置并不发生改变的情况下，产生视觉上的动画效果，从而方便地生成非真实感动画。
