空间滤波与图像锐化技术在质量检测中的应用

Application on spatial filtering and image sharpening for surface quality detection of industrial products

介绍了中值滤波的非线性和在去除图像噪声但能保持边缘不被破坏的特点以及图像锐化技术对图像微分作用后,抽取图像轮廓,对感兴趣的图像特征进行识别的过程.利用这些技术加以综合,对工业产品的表面进行质量检测.

This paper mainly introduces the nonlinear character of median filter, whict is used for blurring and noise reduction without destroying the edge, and also introduces the course that using technology of sharpening to operate the difference coefficient of the image, then extract the outline, and identify the areas we are interested in. These technologies can be integrated to inspect the quality of the surfaces of the industrial products.
