批量计算图像峰值信噪比的matlab代码

我可以回答这个问题。以下是一段可以用于批量计算图像峰值信噪比的Matlab代码:

% Load the images into a cell array
images = cell(1, num_images);
for i = 1:num_images
    images{i} = imread(sprintf('image%d.png', i));
end

% Calculate the peak signal-to-noise ratio (PSNR) for each image
psnr_values = zeros(1, num_images);
for i = 1:num_images
    % Assume image is in the range [0, 255]
    max_val = 255;

    % Calculate the mean-squared error (MSE)
    mse = mean((images{i}(:) - noisy_images{i}(:)).^2);

    % Calculate the peak signal-to-noise ratio (PSNR) in decibels (dB)
    psnr_values(i) = 10*log10((max_val^2)/mse);
end

% Plot the PSNR values
figure;
plot(psnr_values);
xlabel('Image number');
ylabel('Peak signal-to-noise ratio (PSNR)');

% Display the average PSNR value
average_psnr = mean(psnr_values);
fprintf('Average PSNR: %0.2f dB\n', average_psnr);
