+This is a really great paper that is both complex and straightforward.
+This paper "present a robust, real-time video stabilization and rolling
+shutter correction technique based on gyroscopes". I think
+this is a great paper because it makes a clever use of a commodity technology
+(smartphones' gyroscopes) to make a state-of-the-art improvement to a
+central components of phones: video cameras by removing the shakes
+and rolling shutter artifacts of a video in real-time.
