Question: Perform histogram stretching so that the new image has a dynamic range of [0,7]

0

1

$Here, r_{min} = 0 \\ r_{max} = 3 \\ s_{min} = 0 \hspace{1cm} s_{max} = 7 \\ s = s_{max} - s_{min}/r_{max} – r_{min}(r –r_{min}) + s_{min} \\ Therefore,s = 7/3 (r-0)+0 \\ When,r=0 ,s=0 \\ r=1 ,s = 7/3 (1-0)=2.3 ≈ 2 \\ r=2 ,s = 7/3 (2-0) = 4.67 ≈ 5 \\ r=3 ,s = 7/3 (3-0) = 7$ \

Therefore,we have

r=0 | S=0 |
---|---|

r=1 | S=2 |

r=2 | S=5 |

r=3 | S=7 |
