Abstract
Systems and methods for generating an overview for videos by reconstructing a representation of underlying content and linking from points in the overview to specific points in the video. Mechanisms are provided to create three different types of navigable overviews for different types of how-to and instructional videos. A two-dimensional overview is generated when content is two-dimensional, such as instructional videos on electronic whiteboard or other flat content. The three-dimensional overview is created when the content is three-dimensional, such as how-to videos illustrating the use of specific three-dimensional tangible articles. In three-dimensional case, when 3D model is available, the video segments are directly linked to corresponding points on the model. When a model is not available, a rough overview is first created from the captured video and camera orientation metadata. When the user selects a specific location within the overview, the related video segment is automatically played to the user.
