In this paper we study matrix completion based on another low dimensional structure, namely the low rank Hankel structure in the Fourier domain. It is shown that matrices with this structure can be exactly recovered by solving a convex optimization program provided the sampling complexity is nearly...
Rank evaluation plays a key role in low-rank tensor completion and tensor nuclear norm is often used as a substitute of rank in the optimization due to its
Reconstruction of GPS Coordinate Time Series Based on Low-Rank Hankel Matrix Recovery Coordinate time series determined using the global positioning system (GPS) contain annual and semiannual periods that are routinely modeled by periodic si...

impulsivity of pixels and utilized the estimated pixel corruption in the construction of the fuzzy weights used in the averaging process. The methods work well for low mixed noise intensity, but fail when denoising heavily corrupted images due to the inability of ROAD to effectively detect impulses...

Notice that ∥x∥0 is equal to the rank of the diagonal matrix diag(x). The function F ε (x) is equal to (log(1/ε))−1 log(det(diag(x)+ε I))+n, the logarithm of the determinant of the matrix diag(x)+ε I. Hence, it was named as the Log-Det heuristic and used ...

Specifically, a Hankel matrix induced by the observed GPS time series is constructed and proved to be low-rank; subsequently, singular value decomposition and singular value curvature spectrum (SVCS) are applied on the Hankel matrix to recover the low-rank part, namely, the trend and seasonal ...
