This folder contains MATLAB functions for various set operations and for three definitions for erosion on sets.
The sets have to be of the form {(i_1,j_1),(i_2,j_2),...,(i_n,j_n) | where i_1, ..., i_n, j_1, j_n are integers}
This is the case for A, B and U.
C will be given as output in the above mentioned form.
h should be an ordered pair containing integers (x,y).
If A contains (x,y), then, it means that the value in A at (x,y) is 1. If A does not contain (x,y), then, the value in A at (x,y) is 0.
THE OUTCOMES MAY NOT BE AS EXPECTED OR ERRORS MAY OCCUR IF THE INPUTS ARE NOT OF THE SPECIFIED FORM.
