detection of defects meaning in English
缺陷检查
Examples
- Detection of defects in spin - coated resist
自旋涂覆保护层中缺陷检测 - X - ray defect detection is one of the primary methods in non - destructive testing of industrial products and is also widely applied . now , detection of defects in the weld is still done by human interpreter
目前x射线无损探伤系统主要采用人工方式进行在线检测与分析，而人工检测存在主观标准不一致、劳动强度大等缺点。 - In this paper , infrared heat wave image processed by using several typical algorithms of edge detection , from which we conclude that edge detection of defect under the surface of the material is visualized and can be regarded as a reference in ndt
本文通过几种经典的边缘检测算子对热波图像的处理，表明识别缺陷边缘信息直观、可视化程度高，可作为实验结果的参考依据。 - By dividing fabric image into many windows with the same size , choosing a window with minimum local entropy as a region of interest , thresholding the region and filtering out noise through opening function of mathematical morphology , calculating the defect shape factors as recognition parameters , a algorithm and method of detection of defects in fabric is studied : which has advantages of high identification , correctness , and fast inspection speed mainly because it can avoid complicated calculation of whole image and global searching when the feature parameters are extracted
摘要将织物图像分成大小相同的局部窗口，选取局部熵最小的窗口为待研究的感兴趣区域，在此区域内分割出疵点图像并用数学形态学中的开运算滤除噪声，计算疵点形状因子等作为识别参数，研究表明此方法因能避免对整幅图像进行复杂运算，在提取特徵参数时对图像的全局搜索，具有识别正确率高、检测速度快等优点。 - This paper concerns on the application of digital image processing technology to the detection of defect in empty bottle inspection . after concluding the traditional edge detection method , several novel and useful algorithms for the inspection of empty bottle bottom , finish and wall are put forward
