非线性核RX算法(KRX算法)来完成异常目标检测，不仅有效地利用了高光谱图像波段间的高阶统计特性和非线性信息，而且避免了对高维数据的特征提取，从而降低了算法的复杂度．-Nonlinear nuclear RX algorithm (KRX algorithm) to complete anomaly detection, not only the effective use of higher-order statistical characteristics of hyperspectral images and nonlinear information between the bands, and avoid the feature extraction of high-dimensional data, thereby reducing the algorithm complexity.
