greyface1.jpg

在 MATLAB Online 中打开

I = im2double(imread('greyface1.jpg'));

imshow(I);

title('Original Image');

figure();

LEN = 45;

THETA = 15;

PSF = fspecial('motion', LEN, THETA);

blurred = imfilter(I, PSF, 'conv', 'circular');

imshow(blurred);

title('Blurred Image');

figure();

wnr1 = deconvwnr(blurred, PSF, 0);

imshow(wnr1);

title('Restored Image');

figure();

noise_mean = 0;

noise_var = 0.0001;

blurred_noisy = imnoise(blurred, 'gaussian', noise_mean, noise_var);

imshow(blurred_noisy);

title('Simulate Blur and Noise');

figure();

wnr2 = deconvwnr(blurred_noisy, PSF, 0);

imshow(wnr2);

title('Restoration of Blurred, Noisy Image Using NSR=0');

figure();

signal_var = var(I(:));

% Corrected part: Convert to double before using var

uniform_quantization_var = (1/256)^2/12;

wnr5 = deconvwnr(blurred_noisy, PSF, uniform_quantization_var / signal_var);

imshow(wnr5);

title('Restoration of Blurred, Quantized Image Using Computed NSR');

After successfully implementing deblurring using the Wiener filter, my next objective is to determine facial angles and emotions of individuals. Can anyone share code or steps to follow

It's a big, evolving field and of course there are some faces where the emotion is ambiguous or uncertain. Anyway, here are a lot of papers on it. Pick on and code it up. Be forewarned though that the solution is not going to be some simple 300 line script. It will likely be very complex.
