A framework for automatic creation of motion effects from theatrical motion pictures

摘要

Motion effects are the most important physical effects of commercial feature films in the latest cinemas equipped with multi-sensory-effect systems known as 4DX theaters. This paper presents a framework for automatically generating motion effects from a video. We propose a seven-step motion-effect production pipeline based on the concept of structure from motion. In particular, we present the total-variation-based adaptive noise reduction method to remove acceleration noise and introduce methods to estimate the gravity direction from an image. The proposed framework is validated by prototype application to a synthetic video, a commercial feature film, a ride film, and three point-of-view (POV) footages.
