In this paper, we explore the Lambek-Grishin calculus LG: a symmetric version of categorial grammar based on the generalizations of Lambek calculus studied in Grishin [1]. The voca...

We present a closed-form solution for the symmetrization problem, solving for the optimal deformation that reconciles a set of local bilateral symmetries. Given as input a set of ...

We generalize reflection symmetry detection to a curved
glide-reflection symmetry detection problem. We propose
a unifying, local feature-based approach for curved glidereflectio...
