Estimating the Number of Independent Motions for Multibody Motion Segmentation
نویسندگان
چکیده
We study the problem of estimating the number of independent motions for segmentation based on feature tracking. We elucidate the mathematical structure of the problem and present an estimation method using model selection by the geometric AIC, the geometric MDL, and the OIC. We compare their performance using synthetic and real data. We also present techniques for evaluating the reliability of segmentation a posteriori, using the standard F test and model selection by the geometric AIC and the geometric MDL.

Two-View Segmentation of Dynamic Scenes from the Multibody Fundamental Matrix
We present a geometric approach to 3D motion segmentation of multiple moving objects seen in two perspective views. Our approach is based on the multibody epipolar constraint and its associated multibody fundamental matrix, which are generalizations of the epipolar constraint and of the fundamental matrix to multiple moving objects. We show how to linearly solve for the multibody fundamental ma...
متن کاملSegmentation of Dynamic Scenes from the Multibody Fundamental Matrix∗
We present a geometric approach for the analysis of dynamic scenes containing multiple rigidly moving objects seen in two perspective views. Our approach exploits the algebraic and geometric properties of the so-called multibody epipolar constraint and its associated multibody fundamental matrix, which are natural generalizations of the epipolar constraint and of the fundamental matrix to multi...
متن کاملMultibody motion estimation and segmentation from multiple central panoramic views
We present an algorithm for infinitesimal motion estimation and segmentation from multiple central panoramic views. We first show that the central panoramic optical flows corresponding to independent motions lie in orthogonal ten-dimensional subspaces of a higher-dimensional linear space. We then propose a factorization-based technique that estimates the number of independent motions, the segme...
متن کاملAutomatic Camera Model Selection for Multibody Motion Segmentation
We study the problem of segmenting independently moving objects in a video sequence. Several algorithms exist for classifying the trajectories of the feature points into independent motions, but the performance depends on the validity of the underlying camera imaging model. In this paper, we present a scheme for automatically selecting the best model using the geometric AIC before the segmentat...
متن کاملRank estimation in 3D multibody motion segmentation
A novel technique for rank estimation in 3D multibody motion segmentation is proposed. It is based on the study of the frequency spectra of moving rigid objects and does not use or assume a prior knowledge of the objects contained in the scene (i.e. number of objects and motion). The significance of rank estimation on multibody motion segmentation results is shown by using two motion segmentati...
