Exercise $1$: Image enhancement:

You are provided with an image depicted in Figure $1($a$).$ Write Python code to perform the following tasks:

Compute the negative image, as illustrated in Fig $1($b$).$

Enhance the brightness of the input image, resulting in Fig $1($c$)$ and $($d$).$

Enhance the contrast of the input image, resulting in Fig $1($e$)$ and $(f.$

$($a$)$ Original image

$($c$)$ Brightness enhanced with $50$

$($e$)$ Contrast enhanced with $+50$

$($b$)$ Negative image

$($d$)$ Brightness enhanced with $-50$

$($f$)$ Contrast enhanced with $-50$
