Salt & Pepper $(100$ pts$.)$

$1\mathrm{.}1)$ Preprocessing $(50$ pts$.)$

In this part, we will work on the video "shapes$\_$video.mp$4".$ For every frame of the video,

a new card having a specific shape $($star$,$ square, pentagon$)$ appears. However, each frame

has a salt & pepper noise as given in Figure $1.$

Filter each frame to avoid noise and save the video as a new file. To read the video frame by

frame, you can use the following lines.

import moviepy.video.io$.$VideoFileClip as mpy

import cv$2$

vid $=$ mpy$.$VideoFileClip$(\text{'}$shapes$\_$video.avi'$)$

frame count $=$ vid.reader.nframes

video$\_$fps $=$ vid.fps

for $i$ in range$($frame$\_$count$)$:

frame $=$ vid.getframe videofps
