摘　　要：棉花异性纤维的边缘检测是用于提取异性纤维的主要特征,检测的质量直接影响到检测的精度。为此,根据棉花异性纤维检测的特点,利用极值小波变换对目标图像进行降噪和边缘特征处理。经过实验对比表明,该方法明显好于其他方法,说明极值小波变换对提高棉花异性纤维边缘检测精度有重要的意义。Cotton Foreign Fibre thread edge is the most important character in Cotton Fibre thread detection. The quality of edge detection will influence the detection precision directly. Based on the Cotton Fibre thread＇ s character, noise reduction and edge processing is realized with extremum wavelet transform. The result is obviously better than other traditional edge detection operators. It has a great meaning in the improvement of Cotton Fibre thread detection.
