function  DisplayVideo( Data1, Data2, Data3, Data4, imSize, VideoName )
%   This MATLAB code displays video frames of four data matrices.
%
%   Input:
%   Data1-4 = data matrix corresponding to each video
%             We use it in this way:
%             Data1 = original video
%             Data2 = missing/corruption entries support
%             Data3 = corrupted video
%             Data4 = reconstructed video
%   imSize  = size of each frame of videos, i.e., [height,width]
%             (NOTE: they should all have the same sizes.)
%   VideoName = name for the output video file.

writerObj = VideoWriter(VideoName);
writerObj.FrameRate = 15; % FPS: frames per second
open(writerObj);

for i = 1: size(Data1,2)
    
    img1 = Data1(:,i);
    img1 = reshape(img1,imSize);

    img2 = Data2(:,i);
    img2 = reshape(img2,imSize);

    img3 = Data3(:,i);
    img3 = reshape(img3, imSize);

    img4 = Data4(:,i);
    img4 = reshape(img4, imSize);

    h = subplot('position',[0.49,0.50,0.47, 0.42]);
    imshow(img2/255);

    frame = getframe(gcf); % 'gcf' can handle if you zoom in to take a movie.
