1. 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。
unflawed
2. Two-dimensional heat conduction model are presented, the temperature difference of the surface between in the flawed and the unflawed regions for sample of cement is numerically calculated from theory of heat transter.
