报告内容：
A hyperspectral imaging sensor collects hundreds of narrow spectral bands on solar reflectance, and its high spectral resolution offers powerful discriminant capability in separating objects or materials with subtle spectral discrepancy. LiDAR is an active remote sensing technology, using the pulsed laser to measure distances (ranges). LiDAR data products include LiDAR point cloud, Digital Surface Model (DSM), and Digital Elevation Model (DEM), etc. It has been of great interest to fuse remote sensing data from passive and active sensors. In particular, fusion of hyperspectral and LiDAR data has important applications in urban remote sensing. In this talk, feature-level fusion will be focused, where several popular spatial features, such as morphological profile (MP), extinction profile (EP), local binary pattern (LBP), and Gabor features, are studied. These features from both sensors are used for classification with kernel support vector machine (SVM) or kernel collaborative representation classifier (KCRC). The state-of-the-art method based on graph fusion and discriminant analysis is chosen for baseline comparison. Certainly, using the fused data can significantly improve classification accuracy. The experimental results on two sets of urban hyperspectral/LiDAR data show some other interesting results. Some practical considerations will also be discussed.
