I want to embed the video to image then extract the video from that image.I have properly embeded the video to an image.But I am not able to extract.Can provide extractioncode

%THIS IS MY EMBEDVIDEO TO IMAGE CODE

% Read the image and video
image = imread('glioma.jpg');
video = VideoReader('medicine_health_surgery_hospital_729.mp4');

% Read the video frames and resize them to match the image size
numFrames = get(video, 'NumberOfFrames');
videoFrames = cell(numFrames, 1);
for i = 1:numFrames
    frame = read(video, i);
    videoFrames{i} = imresize(frame, [size(image, 1), size(image, 2)]);
end

% Embed the video frames into the image
embeddedImage = image;
bitplane = 1; % Choose the least significant bit (LSB) plane for embedding

tic; % Start the timer

for i = 1:numFrames
    % Extract the bitplane from the video frame
    videoFrame = videoFrames{i};
    videoBitplane = bitget(videoFrame, bitplane);
    
    % Embed the video bitplane into the image
    embeddedImage = bitset(embeddedImage, bitplane, videoBitplane);
end

embeddedTime = toc; % Calculate the embedded time in seconds

% Calculate SNR and PSNR
originalImage = double(image);
embeddedImage = double(embeddedImage);
mse = mean((originalImage(:) - embeddedImage(:)).^2);
snr = 10 * log10(mean(originalImage(:).^2) / mse);
psnr = 10 * log10(max(originalImage(:))^2 / mse);

% Display original and embedded images side by side
figure;
subplot(1, 2, 1);
imshow(image);
title('Original Image');

subplot(1, 2, 2);
imshow(uint8(embeddedImage));
title('Embedded Image');

% Print embedded time, SNR, and PSNR
fprintf('Embedded Time: %.2f seconds\n', embeddedTime);
fprintf('SNR: %.2f dB\n', snr);
fprintf('PSNR: %.2f dB\n', psnr);

% Save the embedded image
imwrite(uint8(embeddedImage), 'embedded_image.jpg');

See attached demo that extracts individual frames from a video and saves them to disk, and then builds a new video from the individual disk images. Adapt as needed.

Hi,

As per my understanding you want to convert a set of images into a video.

You can use the function 'writeVideo' to do the same.

Please refer to the following documentation for more information.

Thanks!
