data(:,:,i)=mean(readFrame(Video1),3);

% Define MHI parameter T

% Compute H(x,y,1,T) (the first MHI)

fst(fst>0) = T;
MHI(:,1) = fst;

% start global loop for each frame
for frameIndex = 2 : size(data,3)
    %fprintf('Loading frame Index %d\n',frameIndex);

    % Load current frame from image array
    frame = data(:,frameIndex);
    frame_pre = MHI(:,frameIndex-1);

    MHI(:,frameIndex) = frame_pre - 1; 

    % Set of all non-zero value to T
    frame(frame > 0) = T;

    [y,x] = find(frame > 1);                

    for i = 1 : size(y,1)                    
        MHI(y(i,:), x(i,:), frameIndex) = frame(y(i,:), x(i,:));
    end
