Use the disk method to find the volume $($in units$3)$ when the region is rotated around the x$-$axis.Given the test image "Lenna" $256256$ with $256$ gray levels, do the following:

Using MATLAB display the test image.

Display the intensity histogram of the test image.

Using the image histogram and cumulative distribution function, locate

the intensity value such that $20\%$ of the output pixels are saturated to $0.$

the noisy image.

Apply smoothing and median filtering to the noisy image and display the

results.

Note: Use the following to copy the image:

$Cp$

homelesalari$/$tenna$.$mat

lenna.mat

Note: You need to write your oun $MAAB$ coles for

all proganming assignments, no builtin functions.

Provide The MATLAB cade with comments and the results.

No build$-$in functions excent the Gaussionmoise.
