(1)Thresholding with T=4

(2)Intensity level slicing with background r1=2 and r2=5

(3)Bit plane slicing for MSB and LSB plane

(4) Negation

4	2	3	0
1	3	5	7
5	3	2	1
2	4	6	7

(i) Thresholding

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

For Thresholding

$S = \begin{cases} L-1, & r \ge T \\ 0, & \text{otherwse} \end{cases}$

Here,L-1=7,T=4

7	0	0	0
0	0	7	7
7	0	0	0
0	7	7	7

(ii) Intensity level slicing with background r1=2 and r2=5:

$S …
