Robust Rotation Synchronization via Low-rank and Sparse Matrix Decomposition

This paper deals with the rotation synchronization problem, which arises in global registration of 3D point-sets and in structure from motion. The problem is formulated in an unprecedented way as a “low-rank and sparse” matrix decomposition that handles both outliers and missing data. A minimization strategy, dubbed R-GoDec, is also proposed and evaluated experimentally against state-of-the-art...

Estimation of Markov Chain via Rank-constrained Likelihood

This paper studies the recovery and state compression of low-rank Markov chains from empirical trajectories. We propose a non-convex estimator based on rank-constrained likelihood maximization. Statistical upper bounds are provided for the Kullback-Leiber divergence and the `2 risk between the estimator and the true transition matrix. The estimator reveals a compressed state space of the Markov...

Path-space Motion Estimation and Decomposition for Robust Animation Filtering

Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence in space, time and among samples. A promising approach pursued in prior work entails subsampling the sequence in space, time, and number of samples, followed by image-based spa...

Robust and Efficient Camera Motion Synchronization via Matrix Decomposition

In this paper we present a structure-from-motion pipeline based on the synchronization of relative motions derived from epipolar geometries. We combine a robust rotation synchronization technique with a fast translation synchronization method from the state of the art. Both reduce to computing matrix decompositions: low-rank & sparse and spectral decomposition. These two steps successfully solv...

Sync-Rank: Robust Ranking, Constrained Ranking and Rank Aggregation via Eigenvector and Semidefinite Programming Synchronization

Abstract. We consider the classic problem of establishing a statistical ranking of a set of n items given a set of inconsistent and incomplete pairwise comparisons between such items. Instantiations of this problem occur in numerous applications in data analysis (e.g., ranking teams in sports data), computer vision, and machine learning. We formulate the above problem of ranking with incomplete...
