Opening morphological operation

WebGREYSCALE OPENING AND CLOSING Greyscale opening is, like its binary counterpart, achieved by first eroding the image with the structuring element, and then dilating the resulting image by the structuring element. The process darkens small bright areas, and may entirely remove very small bright spots like noise spikes. WebThe opening morphological operation removes foreground pixels from the edges of an object in an image and then enhances the remaining pixels. The opening operation can be explained as erosion of the image followed by dilation. It is useful for the removal of internal noise present in an image. The opening morphological operator is applied to ...
