Robust low-rank matrix completion
WebJun 9, 2024 · Abstract. This paper studies low-rank matrix completion in the presence of heavy-tailed and possibly asymmetric noise, where we aim to estimate an underlying low-rank matrix given a set of highly ... WebWe present a new approach to robustly solve photometric stereo problems. We cast the problem of recovering surface normals from multiple lighting conditions as a problem of recovering a low-rank matrix with both missing entries and corrupted entries, which model all types of non-Lambertian effects such as shadows and specularities.

WebDec 20, 2013 · The matrix completion methods assume that the values in the data matrix (graph) are correlated and the rank of the data matrix is low. The missing entries can be recovered using the observed entries by minimizing the rank of the data matrix, which is an NP hard problem. WebSep 18, 2012 · The matrix completion problem consists of finding or approximating a low-rank matrix based on a few samples of this matrix. We propose a new algorithm for matrix completion that minimizes the least-square distance on the sampling set over the Riemannian manifold of fixed-rank matrices. The algorithm is an adaptation of classical …
