WebOpening is an image morphological operation that darkens small objects and entirely removes single-pixel objects like noise spikes and small spurs. Objects tend to retain their original shapes and sizes. The opening operation is erosion followed by dilation. This operation can be applied numerous times to achieve the necessary effect.

Web23 de nov. de 2014 · Remember, an opening is an erosion followed by a dilation where a closing is a dilation followed by an erosion. In terms of analyzing the shapes, erosion slightly shrinks the area of the image while dilation slightly enlarges it. By doing an erosion followed by a dilation (opening), you're shrinking the object and then growing it again. In morphological opening , the erosion operation removes objects that are smaller than structuring element B and the dilation operation (approximately) restores the size and shape of the remaining objects. However, restoration accuracy in the dilation operation depends highly on the type of structuring element and the shape of the restoring objects. The opening by reconstructio…
