Online Scene Text Tracking with Spatial-Temporal Relation
Scene texts in video are not fixed in color, size, format and are easily confused with the background, which imposes significant challenges in video scene text tracking. The trajectories are often be fragmente...

Deduction Theorem for Symmetric Cirquent Calculus
Cirquent calculus is a recent approach to proof theory, whose characteristic feature is being based on circuit-style structures (called cirquents) instead of the traditional formulas or sequents. In this paper...

The Degree of the Quasi-similarity and the Pseudo-metric between Predicate Formulae
The theory of the quasi-truth degrees of predicate formulae is a preliminary test of quantitative predicate logic. Corresponding to quantitative propositional logic, we know that it’s just a beginning. In this...
