accumulateWeighted causes the images to darken

I am using opencv's accumulateWeighted function to get a running average of a camera stream. However I have observed that for lower alpha values < 0.1) the output of the accumulateWeighted functions becomes very dark. Is this is expected behaviour of this function and if not that what am I doing wrong? I am passing it a CV_8UC3 image and receive an CV_32FC3 output which I then display by converting it back to CV_8UC3.

You should initialize dst - the second parameter with the first input image (converted to float)

See example here
