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

2. Bit Plane Slicing

We convert the original image into 3-bit binary image

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

We create three planes from the bit positions
