摘要

We propose a new method for the motion segmentation using amoving camera. The proposed method classifies each image pixel in the image sequence as the background or the motion regions by applying a novel three-view constraint called the "parallax-based multiplanar constraint." This new three-view constraint, being the main contribution of this paper, is derived from the relative projective structure of two points in three different views and implemented within the "Plane + Parallax" framework. The parallax-based multiplanar constraint overcomes the problem of the previous geometry constraint and does not require the reference plane to be constant across multiple views. Unlike the epipolar constraint, the parallax-based multiplanar constraint modifies the surface degradation to the line degradation to detect the motion objects followed by a moving camera in the same direction. We evaluate the proposed method with several video sequences to demonstrate the effectiveness and robustness of the parallax-based multiplanar constraint.
