Question

I have a simple MATLAB sequence which is intended to create an AVI movie from a collection of uint16 images:

video = VideoWriter( vidName );
video.FrameRate = ( frmRate );
open( video );
for i=1:size
    img = imread( picNames(i).name );
    writeVideo( video, img );
end
close( video );

This produces the error IMG must be one of the following classes: double, single, uint8. Any ideas as to how I might get around this without loss of precision or adding compression?

Answer 1

You should add the following line before writeVideo( video, img );:

img=im2double(img);

You will not lose precision.
