Digital Curvatures Applied to 3D Object Analysis and Recognition: A Case Study
Li Chen, Soma Biswas
In this paper, we propose using curvatures in digital space for 3D object analysis and recognition. Since direct adjacency has only six types of digital surface points in local con…

Linear Time Recognition Algorithms for Topological Invariants in 3D
Li Chen, Yongwu Rong
In this paper, we design linear time algorithms to recognize and determine topological invariants such as the genus and homology groups in 3D. These properties can be used to ident…
