This demonstration shows the basic opertors of the mathematic morphology on the binary images or on the gray level image. The structuring element is a 3*3 block (8-connected) or a 3*3 cross (4-connected).
Min (Erosion for binary image)
Max (Dilation for binary image)
Top Hat Bright
Top Hat Dark
Convention: for the binary image, we consider that the object is white.
