dilation=cv2.dilate(image,kernel,iterations=1)# Erode the image erosion=cv2.erode(image,kernel,iterations=1) OPENING 如上所述,这些操作通常组合在一起以获得理想的结果!一种这样的组合称为Opening,其是侵蚀,然后是膨胀 这在降噪中是有用的,其中侵蚀首先消除噪声(并收缩物体)然后扩张再次扩大物体,但噪声将从...

In this tutorial, we will explain the erosion and dilation briefly. Dilation Dilation is a technique where we expand the image. It adds the number of pixels to the boundaries of objects in an image. The structuring element controls it. The structuring element is a matrix of 1's and 0's...
