LiDAR Iris for Loop-Closure Detection
IEEE/RJS International Conference on Intelligent RObots and Systems, 2019In this paper, a global descriptor for a LiDAR point cloud, called LiDAR Iris, is proposed for fast and accurate loop-closure detection. A binary signature image can be obtained for each point cloud after several LoG-Gabor filtering and thresholding ...

On T0- and T1-fuzzy closure spaces
Fuzzy Sets and Systems, 2000Continuing the paper [\textit{R. Srivastava, A. K. Srivastava} and \textit{A. Choubey} [J. Fuzzy Math. 2, No. 3, 525-534 (1994; Zbl 0816.54002)], the authors investigate subspaces, disjoint unions and products of \(T_0\)- and \(T_1\)-fuzzy closure spaces.

Closure spaces and restricted games
Mathematical Methods of Operations Research, 1998Consider a cooperative game \((N,v)\) with transferable utility, where \(N\) is finite. A game with a cooperation structure is the game \((N,v)\) together with a cooperation structure \( P^* \) which associates with each coalition \(S\subset N,\) a partition \( P^*(S)\) of \(S.\) The author considers the restricted game \((N,v^ {P^*}) \) where \[ v^{ P^

The closure of a linear space in a product of lines
, 2013Given a linear space L in affine space $${\mathbb {A}}^n$$An, we study its closure $$\widetilde{L}$$L~ in the product of projective lines $$({\mathbb {P}}^1)^n$$(P1)n.

Place recognition and loop-closure detection are main challenges in the localization, mapping and navigation tasks of self-driving vehicles. In this paper, we solve the loop-closure detection problem by incorporating the deep-learning based point cloud ...

ON THE FORM OF NEIGHBORHOODS IN CLOSURE SPACES
1984Some ultra-general topologists contemplate closure operators which may fail idempotence. As in topology, such an operator u determines (and is determined by) a system of neighbourhood filters: this system satisfies the fourth neighbourhood axiom iff \(u=u^ 2\) (idempotence).

On Quasi-discrete Fuzzy Closure Spaces
Fundamenta Informaticae, 2015This paper studies quasi-discrete closure spaces and fuzzy closure spaces. We show that any topological closure cT induced by a closure c is the smallest extension from a closure space to a topological closure space in both crisp and fuzzy environment, in addition, a characterization of the continuous mappings in quasi-discrete closure spaces is ...
