Determining the Number of Holes of a 2D Digital Component is Easy
Li M. Chen
The number of holes in a connected component in 2D images is a basic invariant. In this note, a simple formula was proven using our previous results in digital topology (Chen 2004,…

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…
