AUTOMATIC CINEMAGRAPHS FROM VIDEO

This document describes techniques to generate a cinemagraph from a video automatically and without user input. The techniques enable accurate determination of moving regions of pixels in the video which are suitable for animation, by determining mask regions using a dense optical flow technique. Described techniques enable selection of frame sequences from the video that provide smooth and engaging animations for the cinemagraph, by looking for pixel motion under particular criteria. Techniques enable multiple independent cinemagraph animations to be smoothly provided in a single cinemagraph image
