i) Digital Negative is calculated by following formula:

$s = intensity_{max} – r$

In given image, $intensity_{max}$ = 7

Therefore, Digital negative = | 5 | 6 | 4 | 0 | 3 | |---|---|---|---|---| | 3 | 2 | 5 | 7 | 6 | | 4 | 2 | 6 | 3 | 1 | | 7 | 3 | 7 | 5 | 4 | | 5 | 6 | 1 | 6 | 3 |

ii) Bit plane Slicing

The given image has maximum grey level of 7, hence it is a 3 bit image.

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

Converting image into binary

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

Separating the bit planes, we obtain

iii) Thresholding

Thresholding of image is obtained using following formula.

s = 1 (r > threshold)

s= 0 (r <= threshold)

Let’s assume threshold to be 2

Therefore, image obtained after Thresholding is –

0	0	3	7	4
4	5	0	0	0
3	5	0	4	6
0	4	0	0	3
0	0	6	0	4
