It is a program that first reads the image in the file named test.tif from the disk and then performs the following operations in order.

Write matlab code.

$1.$ filter the image with median filter of size $55.$

$2.$ Blur in the frequency range with a Butterworth Low Pass filter with a cutoff frequency of $30($where the filter

You can calculate the transfer function with H $=$ lpfilter$(\text{'}$btw$\text{'},$P$,$Q$,30,2).$ P and Q of the zero$-$padded image

is the number of rows and columns$).$

$3.$ Finally, threshold the image using a threshold value of $50$ and display it on the screen.
