NOVEL HYPERSPECTRAL ANOMALY DETECTION METHODS BASED ON UNSUPERVISED NEAREST REGULARIZED SUBSPACE
Anomaly detection Hyperspectral imagery Unsupervised nearest regularized subspace Outlier Removal Local summation Dual-window sliding
2018/5/14
Anomaly detection has been of great interest in hyperspectral imagery analysis. Most conventional anomaly detectors merely take advantage of spectral and spatial information within neighboring pixels....

Nowadays the use of hyperspectral imagery specifically automatic target detection algorithms for these
images is a relatively exciting area of research.An important challenge of hyperspectral target ...
ANOMALY DETECTION IN NOISY MULTI AND HYPER SPECTRAL IMAGES OF URBAN ENVIRONMENTS
Urban Remote-sensing Anomaly detection speckle noise spectral data morphological operation
2015/8/3
The recent surge in remotely sensed imagery with multi to hyper spectral cubes has made it very difficult to detect features because of the sheer volume of data. In a sense it is locating the needle i...

Robust Metric based Anomaly Detection in Kernel Feature Space
Anomaly detection hyperspectral images Manhanlobis distance
2014/4/29
This thesis analyzes the anomalous measurement metric in high dimension feature space, where it is supposed the Gaussian assumption for state-of-art mahanlanobis algorithms is reasonable. The realizat...
In this paper, we proposed a fast and robust unsupervised framework for anomaly detection and localization in crowed scenes. Our method avoids modeling the normal state of the crowds which is a very c...
