Abstract

Motion segmentation is about separating moving objects from the background in video. If the motion is captured by a stationary camera, the solution is trivial. However, if the motion is captured by a moving camera, then the problem is hard to solve. Algorithms proposed so far usually assume the motion of the scene and the camera are both unknown. Consequently, such algorithms are generally computationally expensive and can be fragile for real-time vision applications. In this work, we propose to simplify the problem by using inertial sensors to measure the camera motion directly. The problem can then be simplified considerably, requiring only a simple line fitting algorithm in order to discriminate between the background and the moving objects. We believe the move towards incorporating inertial sensors to vision applications is essential in supporting robust real-time vision applications in future.
