WebIn other words, closing (opening) of a binary image can be performed by taking the complement of that image, opening (closing) with the structuring element, and taking the complement of the result. The hit and miss transform (see also HIPS2 web page) allows to derive information on how objects in a binary image are related to their surroundings. WebWe will explore how to clean, prepare and enhance images using morphological operations. The operations like erosion, dilation, opening, closing, area_opening, and area_closing will be demonstrated. cclg shop
