This paper is focused on building boundary tracing and regularization from raw lidar points. It consists of the following four sequential steps. First, the raw lidar points are separated to ground and non-ground two classes. Next, a moving window is used to segment individual buildings from the non-ground dataset.

By modifying a convex hull formation algorithm, the building boundary points are traced and connected to form an approximate boundary. In the final step, all boundary points are included in a hierarchical least squares solution with perpendicularity constraints to determine a regularized rectilinear boundary.

This paper presents an approach to tracing and regularization of structural boundaries from raw lidar point clouds. The process consists of a sequence of 4 steps: separate structural and non-structural lidar points; segmented lidar points that belong to the same structure; trace structural boundary points; and regularization of the boundary.

In this paper we present a method for building boundary refinement and regularization in satellite images using a fully convolutional neural network trained with a combination of adversarial and regularized losses. Compared to a pure Mask R-CNN model, the overall algorithm can achieve equivalent performance in terms of accuracy and completeness.

The approach comprises four steps: building point segmentation, boundary tracing, boundary grouping, and regularization. In the second and third steps, conventional algorithms are improved for more accurate boundary extraction, and in the final step, a new algorithm is presented to extract nonlinear edges.
