Write a matlab code that first reads the image in the file named test.tif from disk and then performs the following

operations in order.

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

Blur in the frequency domain with a Butterworth Low Pass filter with a cutoff frequency of $30($you can calculate

the transfer function of the filter with $).P$ and $Q$ are the number of rows and columns

of the zero$-$filled image$).$

finally threshold the image using a threshold of $50$ and display it on the screen.
