1- Write a program that takes one image as input and corrupts it by linear motion blur
function with given parameters (motion length and direction).
(a) Consider the noise-free version of the degraded image.
(b) Consider additive Gaussian noise with zero mean and given variance.
- Restore both images obtained in (a) and (b). To find the restoration parameters, you can
implement the first part and if needed the part that handles the noise of the paper by
Ebrahimi and Jamzad.
- To restore the image you can implement the Winner filter.
2- Program exercise No. 5.1 and 5.2 of the book. You should use a graphic tool to construct the
image shown in the book and use it as input.
3. Consider a standard image, add horizontal scan line noise to it (like Fig.5.19 of text book).
Develop a Notch filter to remove this noise.
4. Implement the Homomorphic filter.
- Develop an interactive tool to input the necessary parameters.
- Display both the original and filtered images.
- Calculate the Quality assessment measures such as PSNR and MSSIM to compare the
original and filtered images for different filter parameters.
