Write a MATLAB program that performs a $33$ linear filtering operation on a given gray

level image. Use linear filtering method discussed in the lecture. Do NOT use any

MATLAB built$-$in filtering commands. Test your code with the following filter and

"cameraman.tif" image. Submit the source code, input and filtered images.

Filter

Use your filtering code implemented in Question $1$ and perform a sharpening filtering on

"lena$\_$gray.jpg$"$ image. Use sharpening filtering method discussed in the lecture. Give

the results for two different high$-$boosting constant values. Do NOT use any MATLAB

built$-$in sharpening and filtering commands. Submit the source code, input and filtered

images.
