Exercise $2$: Image enhancement with Gamma correction.

You are provided with an under$-$exposed image depicted in Fig $2($a$).$

$($b$)$ histogrm of gray scal intensity distribution of the image $($a$)$

$($c$)$ Enhanced image with Gamma correection c$=2\mathrm{.}5$

Figure $2.$ Image enhancement with Gamma correction.

Write Python code to enhance the contrast of the input image using Gamma correction, resulting in Fig $2($c$).$

Write Python code to enhance the contrast of the input image using the histogram equalization technique. Additionally, display the histogram of grayscale intensities for the enhanced image.
