Infrared Small Target Detection Via Spatial-Temporal Total Variation Regularization and Weighted Tensor Nuclear Norm
2019
IEEE Access
Preserved Fulltext
INDEX TERMS Infrared patch-tensor model, small target detection, weighted tensor robust principal component analysis, total variation (TV). ...
In this paper, a novel infrared small target detection approach based on tensor robust principal component analysis (RPCA) is proposed by fully utilizing both spatial and temporal information. ...
To solve this problem, an approach based on total variation regularization and principal component pursuit (TV-PCP) is proposed in [33] , since TV regularization can describe the inner smoothness of the ...

This is a scientific strategy for the detection and characterization of extrasolar planets; that is, planets orbiting other stars. ...
As such, it maps out over a 15-year horizon the techniques and capabilities required to detect and measure the properties of planets as small as Earth around stars as large as our own Sun. ...
Likewise, if the astrometric mission fails or turns out to be infeasible, pursuit of space-based direct detection in the final time period would require a sufficiently large η ⊕ based on COROT and Kepler ...
