%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!
