LiDAR-Based Windshear Detection via Statistical Features

Figure 5

Histograms of different distances for the indicator proposed by Huang et al. , where x-label denotes the distance between two feature vectors, and y-label denotes the frequency of the corresponding distance values in all the calculated distances. First column: distances between windshear cases. Second column: distances between non-windshear cases. Third column: distances between windshear and non-windshear cases. Top row: histograms of the Euclidean distance. Second row: histograms of the city block distance. Bottom row: histograms of the Bray–Curtis distance.
