There are different "structuring element" that can run across the image kernel Dilation is image expansion while erosion is image shrinkage. --- Erosion - Dilation -> Opening - Allowing for removing connections due to the loss --- ### Blurring & De-noising > "Sldie a window (of a certain dimension) over every possible" $| -1 | 0 | 1|$
