A slub detection method based on Gabor filters

竹节纱是纺织工业中广泛使用的一种花式纱,为了检测和提取织物中的竹节纱,结合人眼视觉特性,提出了一种基于Gabor滤波器的竹节纱检测方法.根据竹节纱分布的方向特性,利用Gabor滤波器的带通技术,设计了一个目标函数,通过该函数来抑制织物正常纹理的频率成分,增强了竹节纱的频率成分,从而达到了检测竹节纱的目的.大量实验结果表明,该方法获得了较好的检测效果.

Slub is widely used in fabric industry. Incorporating into the human visual characteristic, a slub detection algorithm based on Gabor filters is presented. These filters give consideration to the orientation characteristic of slub. Taking advantage of bandpass technique of Gabor filters, a cost function is designed which can restrain the frequency component of the normal texture of fabric, and strengthen the frequency component of sluh, so it achieves the purpose detecting slub. The plentiful experimental results indicate that the proposed algorithm has gained fine detecting effect.
