| 中文摘要:羽毛片毛杆上的细微折痕缺陷在图像中极易受到噪声干扰。针对细微折痕图像，提出将二维小波变换应用于羽毛片杆细微折痕缺陷检测的方法。这种方法通过二维小波变换图像局部极大值将细微折痕缺陷从图像中准确提取出来。实验证明二维小波变换用来检测羽毛片杆细微折痕缺陷比其他方法更有效。 |

| Detection of Feather Pole Scratch Based on Wavelet Transform Modulus Maximum |

| Abstract:The slight scratch defects of feather pole can be extremely easy disturbed by noise in the image. A defect detection method for the image with the slight scratch, which detects feather pole scratch by two-dimension wavelet transform, is presented. The method uses the local maxima of the image through two-dimension wavelet transform to accurately extract the slight scratch defects from the image. Experiments demonstrate our method which uses two-dimension wavelet transform to detect the slight scratch defects of feather pole more valid than other methods. |
