Web10 de fev. de 2024 · Video. In this article, a Morphological operation called Opening is discussed. Opening operation is similar to erosion in the sense that it also removes foreground pixels from the edges of the image. Opening operation is erosion operation followed by dilation. It is usually used for removing internal noise present inside an image. Webopening = cv2.morphologyEx(img, cv2.MORPH_OPEN, kernel) closing = cv2.morphologyEx(img, cv2.MORPH_CLOSE, kernel) In the next blog, we will discuss other morphological operators like morphological gradient, top hat, etc. Hope you enjoy reading. cypern casino https://aladinweb.com
