Hyperlapse is a new exposure technique in time-lapse photography. It needs to take pictures one by one and take a lot of time in the traditional way. Now we use camera to record long high quality videos and speed up them; however, if the video is shacking, the speed-up process will accentuate the unstable motion, resulting in a nauseating jumble.
Our goal is the hyperlapse videos stabilization. We present an algorithm for choosing the stable frame to replace the target speed-up frame, which is unstable. Our approach use the frame selection technique, we calculate the transformation cost to estimate if the frame is stable or not, by using frame matching for each video frame. Then we use our frame selection method based on transformation cost, this method will consider the transformation cost and target speed-up to make sure our hyperlapse videos is smoothing and the best match a desired target speed-up.
We will compare our result with other hyperlapse method by estimating the transformation of different directions for hyperlapse video, to prove our approach can make the hyperlapse video smoother.(Read More)
