The Algorithm

For every pixel in the image do the following:

If all the following conditions are true

  • 2 <= B(p1) <= 6
  • A(p1) = 1
  • p2.p4.p8 = 0 or A(p2)!= 1
  • p2.p4.p6 = 0 or A(p4)!= 1
    Change the pixel from black to white

    Repeat this process until no changes are done.


    Explaining the Conditions

    Condition1: 2<=B(p1)<=6)

  • B(p1)<= 6 ------> p1 in B(p)


    B(p1) > 6
