Sewing Photos: Smooth Transition between Photos

In this paper, a new smooth slideshow transition effect, Sewing Photos, is proposed while considering both of smooth content transition and smooth camera motion. Comparing to the traditional photo browsing and displaying work, which all focused on presenting splendid visual effects, Sewing Photos emphasizes on the smooth transition process between photos while taking the photo contents into account. Unlike splendid visual effects, the smooth transition tends to provide more comfortable watching experience and are good for a long-term photo displaying. To smooth the content transition, the system finds the similar parts between the photos first, and then decides what kind of camera operations should be applied according to the corresponding regions. After that, a virtual camera path will be generated according to the extracted Region of Interests (ROIs). To make the camera motion smoother, the camera path is generated as a cubic interpolation spline.
