Reference frame for average

Unblur & Summovie

Hi Tim-

Quick question: when unblur outputs an average image, which frame does it use as the reference for the alignment? I.e. is it the first frame, middle frame, etc.?

Thanks,

Hi Greg,

The central frame should always have shift 0, so the output shifts are relative to this.

Cheers,

Tim

Yes for even it is N/2 + 1, for odd it is (N + 1) / 2

You can double check this by looking at the output shifts file, the frame with a 0 shift is the middle frame.
