Original Picture :

>> imshow(i), title('Original Picture');



Blurred Picture :



>> PSF = fspecial('motion' ,13,45);

>> Blurred = imfilter(i,PSF, 'circ','conv' );

>> figure; imshow(Blurred) ; title('Blurred Picture');



Blurred an Noisy Image with Gaussian Methods :



>> PSF = fspecial('gaussian' , 10, 10);

>> Blurred = imfilter(i, PSF, 'symmetric', 'conv');

>> V = .002;

>> BlurredNoisy = imnoise(Blurred, 'gaussian', 0,V);

>> figure;imshow( BlurredNoisy) ; title('Blurred and Noisy Image');
