本文报道了两种不同的方法的调查提取图像的竹节纱从机织物（竹节提取）使用Gabor滤波器。本文提出了两种在时域和频域设计Gabor滤波器的方法。第一种方法根据设计的代价函数在时域中选择较好的滤波器。第二种方法是根据粗节的频率特性，在频域中确定滤波器的参数。真实的机织物图像的实验结果证实了本文提出的两种方法的有效性。后者被认为是优于前者。此外，这两种方法都优于现有的算法上级。
This paper reports the investigation of two different approaches for the extraction of images of slub yarns from woven fabrics (slub extraction) using Gabor filters. We present two methods of designing Gabor filters for extracting slub in both the time domain and the frequency domain. The first method selects a better filter in the time domain according to a designed cost function. The second method obtains the proper parameters for the filter in the frequency domain according to the frequency characteristic of slubs. The experimental results with real woven fabric images confirm the usefulness of the two approaches proposed in this paper. The latter is found to be better than the former. Further, both methods are superior to the existing algorithm.
