This research uses several groups of different cutoff frequencies of low-pass filters for testing to choose the best frequency.

By defining a discriminability function and utilizing some images with synthetic defects, a parameter selection method is proposed to adapt to various fabric types when the Gabor filter bank is applied in defect segmentation. It is argued that only the real part of Gabor filter works during segmentation; the radial orientation can be limited to horizontal and vertical direction; the radial frequency and the length of the FIR filter should depend on the basic frequency of the fabric texture.

本文通过定义分辨力函数，以合成疵点图像为研究对象，提出了在实时应用中对各种不同的纹理图像能快速确定Gabor滤波器组参数的方法：疵点分割中只需用到实Gabor滤波器；方位角只需取水平和垂直方向，径向中心频率和FIR滤波器长度的选取依赖于布面纹理的固有频率。
