Needed Full code for Color to grayscale and Wiener Algorithm for deblurring and differences between Original and Final Deblurred

% Load the original image
Ioriginal = imread('greyface1.jpg');
imshow(Ioriginal);
title('Original Image');

% Define the motion blur point spread function (PSF)
PSF = fspecial('motion', 21, 11);

% Convert the original image to double
Ioriginal = im2double(Ioriginal);

% Apply motion blur to the original image
blurred = imfilter(Ioriginal, PSF, 'conv', 'circular');
imshow(blurred);
title('Blurred Image');

% Restore the blurred image without noise
wnr1 = deconvwnr(blurred, PSF);

% Calculate the absolute differences between the original and restored images
err = imabsdiff(Ioriginal, wnr1);

% Display the restored image
imshow(wnr1);
title('Restored Blurred Image');

% Create a histogram of the absolute differences
figure;
histogram(err);
title('Histogram of Absolute Differences');

We are not here to provide full programs for you.

If you have bugs in your code, describe the error message and we will assist you in understanding the error message.

@Walter Roberson I have directly did from Grayscale image but first i need to Convert RGB to Grayscale and then at last i need to find the difference like how much image data loss happened like that.

For RGB to grayscale, decide what you mean by "gray". This answer covers most things.

IPT rgb2gray() and im2gray() use BT601 luma, if that's what you want.

I don't have a toolbox-independent replacement for deconvwnr(), though you can open it and figure out how it works.

@DGM May i know how to get graph like loss etc.

[DGM]

What loss graph?

[Kartikeya]

@DGM Like suppose if i take original image and final output how much difference happened by pixel by pixel i want to get
