HYPERSPECTRAL ANOMALY DETECTION ALGORITHM BASED ON BACKGROUND RESIDUAL ERROR DATA
基于背景残差数据的高光谱图像异常检测算法

In order to overcome the serious background interferences for small target detection of hyperspectral imagery,a nonlinear anomaly detection algorithm based on background residual error data was proposed.After the background endmembers were extracted,spectral unmixing technique was applied to all mixed spectral pixels to separate target information from complicated background clutter.Then,the unmixing residual error data that included abundant target information was mapped into a high-dimensional feature spa...
