Abstract
Atmospheric turbulence causes objects in video sequences to appear blurred and waver slowly in a quasi-periodic fashion resulting in a loss of detail. A DTW (Dynamic Time Warping) averaging algorithm is presented to extract a single, geometrically improved and sharper frame from a sequence of frames using 2D-DTW. The extracted frame is shown to be sharper over utilizing simple temporal averaging by preserving edges and lines as well as being geometrically improved.
