Combining 5 images from a camera and add them together to yield one image.

Hello I am using the image aquistion toolbox to obtain images froma a camera.

I am set up the capture 5 frames, and I obtain them by

                frame=getdata(vid,5);   %Just get n frames  #
                size(frame)
                class(frame)
      
                

Here are the outputs of size(frame) and class are:

ans =

        1824        2736           1           5
ans =

    'uint16'

The size returns height, width, colourbands, frames

whats the best way to create a composite image where all the images are just added together

I have this but I was hoping fior a faster way:

frames=[];
for i=1:5
  frames=frames+frame(:,:,:,i);
end

You can refer to the documentation of sum function and use the following syntax S = sum(A,dim).

frame = rand(1824,2736,1,5);
frames = sum(frame,4);

The following also may help you depending on the rest of your code: gpuArray, Vectorization.
