  1. Intensity level slicing with background $r_1=3, r_2=5$

    S= $L-1 \ \ \ \ r_1≤ r ≤ r_2 \\ r \ \ \ \ \ otherwise$

    Since the image is 3 bit, L= 23=8

    Here, L-1=7, 3≤ r ≤ 5

    6 2 7 2
    1 7 0 7
    7 7 2 1
    2 7 7 6
  2. Bit Plane Slicing

    We convert the original image into 3-bit binary image

    110 010 011 010
    001 101 000 111
    100 011 010 001
    010 101 111 110

    We create three planes from the bit positions

    1 0 0 0
    0 1 0 1
    1 0 0 0
    0 1 1 1

    MSB plane

    1 1 1 1
    0 0 0 1
    0 1 1 0
    1 0 1 1
    0 0 1 0
    1 1 0 1
    0 1 0 1
    0 1 1 0
