# Matlab Program to Create a Image Deblurring Program Assignment Solution.

## Instructions

Objective
Write a program to create a image deblurring program in matlab.

## Requirements and Specifications Source Code

```DEBLUR function im2 = deblur(im, h)     % First, calculate the inverse values of h     h = 1./h; % We compute the inverse of the values of H since we want to deblur, not blur     [Nf,Mf] = size(h); % size of kernel     n = floor(Nf/2); % half-length of the number of rows of the kernel's matrix     m = floor(Mf/2); % half-length of the number of columns of the kernel's matrix     % Convert the rest of values to -1     hnew = -1*ones(size(h));     hnew(ceil(end/2), ceil(end/2)) = h(ceil(end/2), ceil(end/2)); % keep the original value at the mid-val of the kernel     h = hnew; % Update h     im2 = im; % Store the image in the variable im2     [N,M] = size(im); % Size of the image     for ii = 1+n:N-n % iterate through the rows of the Matrix containing the image         for jj = 1+m:M-m % iterate through the columns of the Matrix containing the image             subim = double(im(ii-n:ii+n, jj-m:jj+m)); % Extract the portion of the image (pixels) to apply the kernel             filtered = subim.*h; % apply kernel             im2(ii,jj) = sum(filtered(:)); % update pixel value         end     end end MAIN clc clear all close all I = imread('corn.tif'); h = ones(1,11)/11; % kernel % Blur blurred = uint8(round(filter2(h, I, 'valid'))); % Deblur im3 = deblur(double(blurred), h); figure subplot(1,3,1) imshow(I, []); title('Original') subplot(1,3,2) imshow(blurred, []); title('Blurred') subplot(1,3,3) imshow(im3, []); title('Restored')```
