Abstract:
In the past few years, graph-based methods have proven to be a useful tool in a wide variety of energy minimization problems. In this article, we propose a graph-based algorithm for feature extraction and segmentation of multimodal images. By defining a notion of similarity that integrates information from each modality, we create a fused graph that merges the different data sources. The graph Laplacian then allows us to perform feature extraction and segmentation on the fused data set. We apply this method in a practical example, namely, the segmentation of optical and LiDAR images. The results obtained confirm the potential of the proposed method.
