Deep Learning Approach for Building Detection Using LiDAR–Orthophoto Fusion
Figure 6
Results of building detection using the proposed method in the testing area: (a) without feature dimensionality reduction, (b) with dimensionality reduction (10 features), (c) example of a detected building through a complete set of input features, and (d) example of building detection after feature reduction by the autoencoder dimensionality reduction approach.
