The automatic extraction of objects from data and images has been a topic of research for decades. This paper proposes an improved snake model that focuses on building extraction from color aerial images and light detection and ranging (LiDAR) data. A snake is defined as an energy minimizing spline

In this paper we present a novel approach for building detection from multiple aerial images in dense urban areas. The approach is based on accurate surface reconstruction, followed by extraction of building façades that are used as a main cue for building detection. For the façade detection, a simp
